Question

define relative density. give its mathematical formula.

Answer 1

Relative density, or specific gravity, is the ratio of the density (mass of a unit volume) of a substance to the densityof a given reference material. Specific gravity usually means relative densitywith respect to water.

Answer 2

Heya...!

The ratio of density of the substance to the density of water at 4℃ is known as relative density of the substance

Relative Density of a subtance
RD = density of subtance/density of water at 4℃

Relative density has no units it's a pure number
