Density is usually expressed in units of grams per milliliter (g/mL). • Density is a measure of how tightly matter is packed. • Osmium, a blue/white metal, is the densest substance on earth! • A piece of osmium the size of a football is to heavy to lift.
Density can be used to identify substances • The density of each sample will not vary. • Densities can be used to determine whether a given material will sink or float. • Float= density lower than the medium • Sinks= density is greater than the medium
