About how many atoms are in the average human body?

That may be right, but the website just says that its 7 X 10^27-it doesnt explain how they figured it..\n\nSo lets see if we can figure how they got that number: There are 6 X 10^23 atoms per mole.  Lets say the average atom (most being hydrogen-1, followed by oxygen-16, and carbon-12) has a molar weight of 7.  So, 6 X 10^23 average atoms in the body would weigh 7 grams.  To get 70 kilograms, we have to multiply that by 10,000.  So, 2000 times 6 X 10^23 gets us about 6 X 10^27.  That's pretty close to 7 X 10^27.  I have a feeling that the real average molar weight per atom would be quite a bit smaller than 7, though.

"...while the adult skeleton contains 206 bones, the skeleton of an infant contains 350 (the bones fuse together as you grow). And more than half of your 206 bones are found in your hands and feet."

The average human body contains approximately 6 quarts (or 5.6 liters) of blood\n\nso I would say that movie had about 20-30 quarts

The answer is 206 \n\nThe "adult" human body has 206 bones. At the time of birth a child has 300 bones but these bones fuse with each other as the child grows up and at adulthood the figure drops to 206.

average human body has 206 bones.  Some have one or two more or less.\n\nas for the joints, I've only had one today...

"...the number of atoms in the observable universe can be estimated to be between 4×1078 and 6×1079. However, because of the possibly infinite nature of the universe, the total number of atoms in the entire universe may be much larger or even infinite."\n\nThis website for confirmation and more info --> http://www.biocrawler.com/encyclopedia/Atom

Look on a periodic table.\n\nIt should be listed below the atomic number as a decimal value.  The mass number is an average mass (in atomic mass units) of an element, based on different isotopes.  It equals the number of protons + the number of neutrons in the nucleus.

there is no such absolute number.\n\nDepends on the person, body size, lung capacity, and lung contractility

For C, that would normally be true.\n\nFor D, the answer is 1.2X10^24 atoms.\n\nFor E, helium atoms escaped through effusion.

First of all, look on your periodic table.  Somewhere there should be a listing for atomic mass.  Usually it's either at the very bottom of the square for that element or in a separate table.  That is how much that atom weighs in amu, or atomic mass units.  A molecule weighs as much as all the atoms in it put together.\n\nA guy named Avogadro came up with a number called Avogadro's number (modest character, wasn't he?) or a mole.  A mole is 6.023 * 10^23.  There are exactly one mole of amus in a gram.  Atoms are commonly measured in moles in the lab as well, since the actual number of atoms is usually way too high to work with conveniently.\n\nSo to answer your question, the number of atoms in a sample is (6.023 * 10^23 * the number of grams)/the atomic mass.  The number of molecules is (6.023 * 10^23 * the number of grams)/the sum of the atomic masses of the component atoms (also called the molecular mass).  But most of the time, amounts are reported in moles, and the number of moles is simply the number of grams/the atomic or molecular mass.\n\nI hope that made sense to you.

This is a problem. Medical dictionaries define an organ as a relatively independent part of the body that carries out 1 or more special functions. Lists of internal organs usually list 22. The skin would make 23. Eyes and ears are certainly organs and in the skin are sense organs. So there isn't a definite answer or an official answer.

At birth the human body has about 350 bones, but by the time adulthood arrives, some of the bones have fused together to give us a total of 206 bones in an adult body.

In scientific terms atoms are the smallest possible particle of a chemical element that retains its chemical properties. All atoms are made of the same basic elements, protons, neutrons and electrons , but each of the individual elements are made from different organizations of these materials. The basic structure of an atom is the nucleus, which is made of protons and neutrons (except hydrogen which only has a proton), and the electrons which, to over simplify it, "orbit" the nucleus. Elements are defined however by the number of protons in the nucleus, carbon always has 6 protons in it's nucleus, oxygen always has 8.\n\nAtoms are found EVERYWHERE. Everything you are, the air you breath, the things you smell, are all made of atoms, as others have said, it is the basic building block of everything, literally nothing would exist without them.\n\nIsotopes, contrary to what was said above, are in fact atoms, just a special kind of atom. The have the same amount of protons in their nucleus, hence they stay the same kind of element, but the have a different number of neutrons. I said above that hydrogen doesn't have a neutron in it's nucleus, and a standard hydrogen atom doesn't, but an isotope of hydrogen does, it's called deuterium, and it has 1 proton and 1 neutron in it's nucleus.\n\nDon't feel bad if you don't get it still, it really takes a class in chemistry to really get a handle on what exactly it all means. Good luck.

The cell is still made up of many atoms, thats the only irrefutable link there. And the atom is not the elementary essential of matter, if by elementary essential you are referring to the smallest constituent of a matter. Atom is made of of sub-particles: protons, electrons, neutrons, quarks... And these are further made up of smaller sub-particles (our knowledge are always limited). Proton and nuetron have masses and volumes. Doesnt that mean they are matter too?

206 Bones in the human Body would be be my guess...

In an average healthy adult, the volume of blood is about one-eleventh of the body weight. Most sources state the volume of blood in an average human adult, who is between 150 to 160 pounds, as between 4.7 and 5 liters, although the more recent sources state the volume of blood in an average adult as 4.7 liters. Sources state that an 80-pound child had about half that amount, and an 8-pound infant has about 8.5 ounces.In an average healthy adult, the volume of blood is about one-eleventh of the body weight.
