Question

what is relative density? write its SI unit.​

Answer 1

Answer:

mass per unit volume is called density .

SI unit kg/ m3

it is dimensionsless quantity and has no unit .relative density is ratio of density ( mass of unit volume ) of a substance to density of given reference material . specific gravity usually means relative density with respect to water.

Answer 2

Explanation:

Relative density 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 a dimensionaless quantity and it has no S.I unit. sooo,, the S.I unit of density is: Kg/ m^3
