How do you find the density of wood?
341105
Density is mass divided by volume.  The mass of the piece of wood is very easy to measure.  The volume, however, may not be so easy.  Perhaps the easiest way to measure volume, especially if the wood is an odd shape, is to submerge it in water, and measure the amount of water which is displaced by the wood.

This is how you do it.\nYou need to find out the mass of hexane first. Calculate the mass of hexane by subtracting the mass of empty beaker from the mass of beaker with hexane. Once you obtain the mass of hexane, divide it by the volume which is 5ml. You will get your density in units g/ml. I hope this was enough help. E-mail if you need more than this.

Find the weight the object (with a precision scales) and its volume (put it in water and look at the amount displaced).\n\nCalculate the density = weight (in gram) / volume (in milliliter)\n\nYou will find a number lying between 19.3 (density of pure gold) and 8.92 (density of pure copper). Say you found 18 gram/ml\n\nThen the amount of gold is   (18-8.92)/(19.3-8,92) = 87.5% gold

Density = mass/volume\nDensity = 615/105 gm/cm3 = 5.86 gm/cm3

This can be done with a density gradient column.  It is made of 2 fluids that are carefully mixed so that the density of the mixture varies from the top of the container to the bottom.  An object will then come to rest where its density matches the mixture.  This is actually a very accurate way of determining the density of materials.  However, over time the fluids in the column mix by diffusion and will eventually cause the suspended objects to sink or float.

You just need the density of sugar. That will give you the weight/vol.\nDivide 1g by the density will give you the volume of 1g.\n\n Then take the cube root of the volume to find the size of the cube.\n\nI search and found the density to be 1.6 g/cm^3\n\nso, if it were 1 g/cm^ the cube would be 1 cm on a side\nif it were 2 g/cm^ the cube would be (1/2)^(1/3) on a side.\n\nJust calculate (1/1.6)^(1/3) = s length of side of your cube in cm.

To determine density you also have to know the temperature.  The colder a substance gets, the more dense it becomes (ie. the particles come closer together).  Water is the one odd ball, it becomes most dense at 4 degree C instead of below freezing like most substances.

Yes, you can get very many experiments on density. Depends on what you want to do with density. If you want to compare the densities of to different solids in relation to a particular liquid (e.g water) You just measure their dimensions and divide their  mass by their volume to get their density (If you don't know already) . Then you find their Relative density using the equation.

ya you would just go density divided by the mass and then you get the volume  make sure you density is grams/ml and then your mass should be ml and then your volume would turn out to be grams. good luck

Well, what quality to you want to measure -  size?  The weight?  The density?

I'll agree that you need help.  Density is mass/vol.  You've given the density, you need another value to calculate the remaining value.

Density = 13.5 g/cm^3\n13.5 g = about .0297 pounds\n\n4/.0297= about 134.52 cm^3, or 134.52 milliliters.

Density - 1.151 \nNot easy to find

All you need to do is know the density of water- not too difficult to find! THe psi necessary to support a column then must match the weight of that column. So, if a column is 1inch in area and Hinches high, if you know D the density of water per cubic inch in pounds, the height of the column in inches times this value is the psi needed.\n\nPressure psi=H*D\n\nThis also works for metric, just use cms and kgs as the base sizes.

You need to know the density.

You must to know the density, d. Then use the formula m = vd and you will know the mass of compound. Divide m by M (molar mass) and this is number of molles, n\n   n = vd/M

Density is simply mass per unit volume.  The density of a substance is directly related to the atomic weight of the element composing it, ie., elements with higher atomic weight can be thought of as being “heavier”.   Another way of stating this is that equal volumes of two different substances have different densities because each different substance has a different mass (ie, atomic weight) and crystal structure.  There are many types of units which can be used to measure the mass of a substance (pounds, grams, etc.), just as there are many types of units which can be used to measure volume (cubic feet, cubic centimeters, etc.).  The standard units of measure for density are grams/cubic centimeter.  \n\nDifferent minerals or rocks can vary greatly in density, depending on their chemical make up.  Density is such a characteristic property of a substance that it may be used to identify the substance.  Geologists have found it useful to develop a system of comparing densities of different minerals or rocks by calculating a numerical value without units known as “specific gravity”.  The specific gravity is the weight of a substance compared to an equal volume of water.  Water is chosen as the substance for comparison because by definition it has a density of 1 gram per cubic centimeter (at 4o C), and also because it is such a common substance.  For example, compare the density of a rock like granite to water:  a cubic foot of water weighs 62.5 pounds and a cubic foot of granite weighs 168 pounds.  The specific gravity of granite is:   168 / 62.5  =  2.7.   Granite is 2.7 times heavier than water.
