WebDensity. Density is a measure of how much mass there is in a given volume or amount of space. The density of any substance is calculated by dividing the mass of the matter by the volume of the matter. In Fig. 2.2, volume is represented by boxes and individual particles of matter are represented by colored shapes. Box A has five spheres.
