WebWater is a relatively compact substance, and it ordinarily has a density of 1 g/cm 3. Materials float on water if they have a density less than 1 g/cm 3 and sink if their density is greater than 1 g/cm 3. Cork floats on water because it has a very low density of about 0.2 g/cm 3. It is much less dense than water. WebDensity is the ratio of the mass to the volume of a substance:. ρ = m/V [1] where ρ = density, units typically [g/cm 3] or [lb/ft 3] m = mass, units typically [g] or [lb] V = volume, units typically [cm 3] or [ft 3].
