Question

diatinguish between density and relative density

Answer 1

Hiiiiii machiiii ✋..

➡️ Relative density, or specific gravity, is the ratio of the density (mass of a unit volume) of a substance to the density of a given reference material. Specific gravity usually means relative density with respect to water. It is defined as a ratio of density of particular substance with that of water.

Answer 2

Density- Mass per unit volume is called density .
Density= mass/ volume


Relative density- The ratio between density of a substance and density of water is called relative density.
R. density= density of substance/density of water
