Question

Differentiate between Density and Relative density

Answer 1

Density-the density of the object is defined as a mass of a unit volume.
Relative density-it is the ratio of the density of the object to the density of the water.

Answer 2

density is defined as mass per unit volume.
relative density is defined as ratio of density of substance to density of water.
S.I unit of density is kg/m³.
relative density doesn't have S.I units.
