• Density is defined as mass per volume. Density of a material is the amount of substance contained in unit volume of the material. SI unit of density is kg/m³.

• Relative density is the ratio of density of a substance to the density of a reference material. Usually, the reference material is water. Relative density is also known as specific gravity.

Answer 2

Explanation:

Density is the property of matter represented by a ratio of mass to a unit volume of matter. Specific gravity which is also called as relative density is a measure of density with respect to a density of pure water.
