Question

Define Relative density with its formula and SI unit.​

Answer 1

Answer:

Relative density is the ratio of density of a substance to the density of water at 40 C .Since the units for both the numerator and denominator are same, they cancel each other. Thus relative density has no units. Density is defined as mass per unit volume. Hence its SI unit is: kg/m3.

Answer 2

Answer:

Relative density is the ratio of density of a substance to the density of water at 40 C .Since the units for both the numerator and denominator are same, they cancel each other. Thus relative density has no units. Density is defined as mass per unit volume. Hence its SI unit is: kg/m3.

Relative density can be calculated directly by measuring the density of a sample and dividing it by the (known) density of the reference substance. The density of the sample is simply its mass divided by its volume.
