Density is a physical property and not a chemical property because  density changes with respect to change in the states of matter. In  Solid, Liquid and Gas respectively, t â¦ he density changes. For  example, water, ice and water vapour have different densities.
The mass density has the units mass/volume. Since volume has the units length cubed then the SI unit of mass density is kg/m 3. More common units of density are g/ml or g/l. Substances have differnt densities. In fact the density of a substance can often be used to help idenify it.
