Density of a substance is a useful property as it determines whether the substance can float on water. If the density of a substance is less than the density of water, it floats on water; else, it sinks. The density of water is 1 gram per centimeter cubed. It is used as a standard in calculating relative densities of various substances. Relative density is defined as the ratio of the density of a substance to the density of water.

• A:

Mass is equal to density times volume, or m = Dv, since density is equal to mass divided by volume, or D = m/v. Mass is denoted by the symbol "m," and its SI units are kilograms.

• A:

The formula for density, which is mass divided by volume, can be manipulated to have the volume as the unknown. Given the mass and the density, the volume can be found by dividing the mass by the density.

• A:

To use the known mass of a substance to calculate the volume occupied by that substance, divide the mass by the density of the substance. The units in which density is expressed must be the same as those used to measure mass and the volume.
