| Density (symbol: ρ - Greek: rho) is a measure of mass per unit of volume. The higher an object's density, the higher its mass per volume.
Density is defined as mass divided by volume, or mass per unit volume. The density in kilograms per cubic meter can be obtained by multiplying the table values by 1000. The densities of most of the pure elements can be found in the periodic table of the elements.
