Define density and specific gravity. Perform calculations involving both density and specific gravity.
Density. Specific gravity. Density is the mass-to-volume ratio of a substance. Density is a physical characteristic of matter. Each substance has a characteristic density that can be used as one hint in identifying a substance. Gases have very low density, usually expressed in g/L.
