ABSTRACT
Density, p (kg/m3), is the mass of a substance per unit volume. The molar volume of a substance, V m (m3/mol), is a related property. The density is related to molar volume by:
where p M vm
=density, kg/m3 = molar mass, kg/mol = molar volume, m3/mol

The specific gravity, dnrrz, is the density of a substance at temperature T1 relative to the density of water at T2• Usually, the reference density is that of water at 4°C, 1.0000 g/cm3.
