The letter D stands for density, m for mass, and V for volume. The SI unit of density is kg/m 3 but it will suffice in the lab for us to use g/cm 3 (remember, 1 cm 3 = 1 mL so 1 g/cm 3 = 1 g/mL). The measurement of density requires two pieces of data and therefore requires great care in the making of both measurements so as not to lose precision.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.
