Question

Relation between density ($\rho$), relative density $r$, and density of water ${\rho }_o$ is given by:

• A. $r=\frac{\rho }{{\rho }_o}$
• B. $r=\frac{{\rho }_o}{\rho }$
• C. $r=\rho {\rho }_o$
• D. $r=\frac{\rho }{{\rho }_o^2}$

Answer 1

The correct option is A $r=\frac{\rho }{{\rho }_o}$

Relative density is defined as the ratio of density of substance to the density of water.

$\therefore$ Relative density, $r=\frac{\rho }{{\rho }_o}$
