Density is specifically defined as the ratio of a substance's mass to its volume: Density = Mass Volume (2.1) (2.1) D e n s i t y = M a s s V o l u m e. The S.I. unit of density is kg/m 3, but in chemistry it is more often expressed in units of g/cm 3 for solids, and g/mL for liquids and solutions.Description. This lab helps drive home the point of "density is mass divided by volume." It shows students what happens when they change volume but keep mass constant, when they change mass but keep volume constant, and when they change both of them.
