Density is how much mass something has for its volume.
The lab technician measured the density of the liquid.
The density of a substance can be measured in a laboratory.
Let's test the density of that wallboard with this two by four.

Mrs.Tuft used a hydrometer to determine the specific gravity of a liquid
I'm seriously concerned about the sudden increase in the population density of this area.
Foam has a lower density than water, so it floats.
The student's report included density-dependent factors that showed how the size of the population varied with the density of that population.
This room has to much mass. Mass is a synonym for density. I guess
Black holes have an insanely huge density (aka they are very dense).
