Can i define a mole in the following manner?

The first part is correct.  If the numbers in the second part are correct, it is true only for an ideal gas.  Other materials have various densities in their liquid and solid states.

If you have a family, why do you describe it with more than one number? The weight of the family, and the number of family members?\n\nThe number of moles is just the number of particles. The mass is the amount of material.

OK - chemists are basically lazy (that's why we use symbols for elements and formulas for compounds; we don't really like to write that much.)\n\nThe mole is a shortened way to indicate a really big number.\n\nIf I said to you, 1 dozen, you would know I am talking about 12 of something (doesn't matter what, its still 12).\n\nIf I said to you, 1 pair, you would know I am talking about 2 of someting (doesn't matter what, its still 2)\n\nIf I said to you, 1 mole, you would know I am talking about\n602200000000000000000000 of something (doesn't matter what, its still that much.) This is usually written as 6.022 x 10(23)\nbecause we are not about to keep track of all those zeroes.  If I told you your allowance was 1 mole of dollars you would be very rich because you would have 6.022 x 10(23) dollars. (Remember me in your will).\n\nAtoms are too small to see so we have to work with A LOT of them and everyone has agreed on a "standard" number of atoms, 1 moles worth, also called "Avogadro's number".  You could have less than that (0.5 moles, 0.456 moles) or more (10 moles, 540 moles etc.) but the "standard" for comparison is 1 mole.\n\nSo, for your project, figure out how many "whatevers" it takes to go around the world and then divide that number by 6.022 x 10(23) and you will know how many moles of your "whatever" you need.

I would consult a dermatologist or two.\nIt would think it would be dependent not only the circumference of the mole, but the depth of it as well that would need to be removed.\n\nAsk an experience doctor of dermatology.

i believe its called "The mole"

The "amount" of each compound present in the reaction.  While most will tell you that it technically is in terms of "moles", it can just as easily be thought of as a recipe.  \nIf you wanted to create a particular substance in the lab, these amounts would give you an idea of the amount of reactants needed to synthesize the end material.

Let's see...it's desireable because it's likely to be a lot different than your starting material and your derivatizing agent - this gives you confidence that you actually made a derivative and are not just measuring the m.p. of either your unreacted agent or your starting material.  We used this a lot when I took a class called the Analysis of Organic Unkowns.  No instruments were allowed.

Chemical equations show the molecular composition of compounds in a balaanced form between reactants and products. These are expressed in moles, or number of molecules, rather than mass. By matching the number of molecules needed for a reaction the result can be controlled better than if only mass were used. Excess or limited amounts of one element in a reaction might cause the product to be different than intended. Ultimately, a chemical engineer will convert the specifications to mass, but unless the molarity of the raw material is known this cannot be done properly.

6.02 x 10^23 is the conversion for converting from moles to # of molecules or atoms.\n\nWhen you use the number 19, you are counting the number of atoms in a molecule, not the number of molecules in a mole.

I have a small mole on my left breast.

A mole or melanocytic naevus is a small, dark spot on the skin. It can be subdermal made of melanin, or a pigmented growth on the skin, formed mostly of melanocytes. The high concentration of melanin is responsible for their dark color. They are a member of the family of skin lesions known as naevi.\n\nMoles may either be present at birth or develop later in life.\n\nAcquired moles are a form of benign neoplasm, while congenital moles are considered a minor malformation, or hamartoma. Moles are most often of no medical consequence, but since they are permanent, they may occasionally be removed for cosmetic or other reasons.\n\nMoles are usually circular or oval and not very large. Most children are born with moles, and almost everyone has at least one or two moles on their bodies. Large amounts can be concentrated on the back, the chest and arms.

Your skin color is produced by melanocytes, the cells which contain the pigment melanin. A mole is a tight cluster of melanocytes with a high concentration of melanin. \nAlmost everyone is born with at least one mole on their body. The moles that are acquired throughout life are suspected to be caused by exposure to ultraviolet light, which changes the DNA of the skin and lets the melanocytes grow in these tight clusters. Some people also inherit moles, in which case they may have over 100 moles on their body. \nTypical spots for mole formation are usually on the back, chest and arms (but also other regions which are exposed to sunlight, especially the face and hands). \nThe majority of melanomas (skin cancer) do not form from an exisitng mole, but rather create a new growth on the skin.

Moles, known medically as nevi, are clusters of pigmented cells that often appear as small, dark brown spots on your torso, face, arms and legs. But moles can come in a range of colors and can develop virtually anywhere, including your scalp, armpits, under your nails, and between your fingers and toes.\n\nMost people have between 10 and 40 moles, although the number you have may change throughout life. New moles can appear into mid-adulthood, and because moles last about 50 years, some moles may disappear as you age.\n\nThe great majority of moles are harmless, but in rare cases, moles may become cancerous. Monitoring moles and other pigmented patches is an important step in the diagnosis of skin cancer, especially malignant melanoma. Although not all melanomas develop from pre-existing moles, many begin in or near a mole or other dark spot on the skin.\n\n\nEveryone has moles, sometimes 40 or more. Most people think of a mole as a dark brown spot, but moles have a wide range of appearance. \n\nAt one time, a mole in a certain spot on the cheek of a woman was considered fashionable. Some were even painted on. These were called "beauty marks." However, not all moles are beautiful. They can be raised from the skin and very noticeable, they may contain dark hairs, or they may be dangerous. \n\n\nNormal Mole \n\nMoles can appear anywhere on the skin, alone or in groups. They are usually brown in color and can be various sizes and shapes. The brown color is caused by melanocytes, special cells that produce the pigment melanin. \n\nMoles probably are determined before a person is born. Most appear during the first 20 years of a person's life, although some may not appear until later in life. Sun exposure increases the number of moles. \n\nEach mole has its own growth pattern. At first, moles are flat and tan, pink, brown or black in color, like a freckle. Over time, they usually enlarge and some develop hairs. As the years pass, moles usually change slowly, becoming more raised and lighter in color. Some will not change at all. Most moles will slowly disappear, seeming to fade away. Others will become raised so far from the skin that they may develop a small "stalk" and eventually fall off or are rubbed off. \n\nThis is the typical life cycle of the common mole. These changes occur slowly since the life cycle of the average mole is about 50 years. \n\nMoles may darken, with exposure to the sun. During the teen years, with birth control pills and pregnancy, moles often get darker and larger and new ones may appear. \n\nDifferent Types of Moles\nRecent studies have shown that certain types of moles have a higher-than-average risk of becoming cancerous. Some may develop into a form of skin cancer known as malignant melanoma. Sunburns may increase the risk of melanoma. People with many more moles than average (greater than 100) are also more at risk for melanoma. \n\nMoles are present at birth in about 1 in 100 people. They are called congenital nevi. These moles may be more likely to develop a melanoma than moles which appear after birth. When a congenital nevus is more than eight inches across, it poses the greater risk for developing melanoma. \n\nMoles known as dysplastic nevi or atypical moles are larger than average (usually larger than a pencil eraser) and irregular in shape. They tend to have uneven color with dark brown centers and lighter, sometimes reddish, uneven borders or black dots at edge. These moles often run in families. \n\nPersons with dysplastic nevi may have a greater-than-average chance of developing malignant melanoma. These people should be seen regularly by a dermatologist to check for any changes that might indicate skin cancer. They should also learn to do regular self-examinations, looking for changes in the color, size or shape of their moles or the appearance of new moles. They should also shield their moles from sun exposure using sunscreen and/or clothing. \n\nRecognizing the ea

OK, but you need to look up atomic weights or calculate molar mass.\n\n   Grams = Moles x molar mass  OR  moles x atomic mass\n\n    Moles = Grams/(molar mass) OR Grams/(atomic mass)

A mole is an agent in the enemies camp. a spy that is spying basically.\nMore accuratly, it is often used to refer to a person that is deeply embedded inside an organisation, thus having access to the information in the inner workings deep in the organisation.\nThus... they have dug into the top part and are a mole...

Itching & hair loss wouldn't be the primary symptoms.  Instead, use the ABCDE method, as follows:\n\nA-Asymmetrical - the mole would not have a simple shape, but would be distorted and unusually shaped.\n\nB-Borders - the mole would not have a clear, sharp border on its edges, but would be fuzzy and faded on the outside\n\nC-Color - the mole may be multi-colored, or have different shades of the same color mixed in.  It would not be one similar color throughout.\n\nD-Diameter - the mole should be fairly large in size (somewhat larger than the eraser on the end of a pencil), and would grow larger with the passing of time\n\nE- Elevated - the mole may have a raised appearance, as opposed to a flat and level appearance.\n\n\nOf course, this is a general guide, and there are different types of skin cancer that present themselves differently.  So if you have anything that looks suspicious, see a dermatologist for his/her expert opinion right away.  Don't put it off - skin cancer can be deadly if ignored for too long.\n\nGood luck to you.  Hope this helped

The Mole was not so much "discovered", but arbitrarily created. (Much like any other unit of measure). All this means is that scientists agreed upon a specific amount that will represent 1 mol of a substance. This amount was related to every element based on its average atomic mass value, which in the case of moles is named the molar mass. Each element has a different molar mass, which is why 12g of carbon is one mole, whereas 12g of oxygen is only 0.75 moles.\nOne mole represents a value of 6.022x10^23 atoms of elements, or 6.022x10^23 molecules of a substance. This number is Avogadro's number, and is the "number" behind a mole.\nAs this is an SI unit (Système Internationale) I believe this concept was first introduced by French Scientists.
