Density Worksheet Name._KS"_;__—_ Section_____________ Chemistry 101 Density is the ratio of the mass of the substance to the volume of the substance at a given temperature. Density has units of g/ cm3 or g/c.c. or g/mL for liquids and solids, and g/L for gases. Density is an intensive property. Density varies with change in temperature. 1.
