Question

define the term relative density of a substance?and what is the unit of relative density?​

Answer 1

Explanation:

Relative density is the ratio of density of a substance to the density of water at 40 C . ... Density is defined as mass per unit volume. Hence its SI unit is: kg/m3.

what is the unit of relative density?

$\huge\color{Red}\boxed{\colorbox{black}{♡Answer ♡}}$

1) Relative density, or specific gravity, is the ratio of the density of a substance to the density of a given reference material. Specific gravity for liquids is nearly always measured with respect to water at its densest; for gases, the reference is air at room temperature.

2) Relative density is the ratio of the density (mass of a unit volume) of a substance to the density of a given reference material (i.e., water). It is usually measured at room temperature (20 Celcius degrees) and standard atmosphere (101.325kPa). It is unitless.
