To determine the mass of gold, we simply multiply the density and volume. Density is a value for mass, such as kg, divided by a value for volume, such as m3. Density is a physical property of a substance that represents the mass of that substance per unit volume. We do as follows:
mass = density x volume mass = 19.3 g/cm^3 ( 16.0 cm^3 ) mass = 308.8 g
