Which Metals Are the Heaviest? | Sciencing
Apr 10, 2018· The density of a material is mass per unit volume. Density is measured in kilograms per cubic meter (kg/m 3) or grams per cubic cm (g/cm 3). Density affects how different materials interact. For example, many types of metal sink in water because the metal has a higher density (i.e., it is more dense) than water.
