Question

Relative density is a unitless quantity

• A. True
• B. False

Answer 1

The correct option is A True

Relative density

1. Relative density is the ratio of the density of a substance to the density of given reference material, ($RD=\frac{{\rho }_{subs\tan ce}}{{\rho }_{referencematerial}}$).
2. The SI unit of density is $kg/m^3$.
3. Since relative density is the ratio of two densities, it is unitless.

Hence, the given statement is true.
