Question

Formula for density and relative density/ specific gravity respectively are:

• A. $\rho =\frac{m}{v}$, $\sigma =\frac{{\rho }_{liq}}{{\rho }_{water}}$
• B. $\rho =\frac{v}{m}$, $\sigma =\frac{{\rho }_{water}}{{\rho }_{liq}}$
• C. $\rho =\frac{m}{v}$, $\sigma =\frac{{\rho }_{water}}{{\rho }_{liq}}$
• D. $\rho =\frac{v}{m}$, $\sigma =\frac{{\rho }_{liq}}{{\rho }_{water}}$

Answer 1

The correct option is A $\rho =\frac{m}{v}$, $\sigma =\frac{{\rho }_{liq}}{{\rho }_{water}}$

Formula of density-

$\rho =\frac{m}{v}$

$\rho$; density

$m$; mass of the object

$v$; volume of the object

Formula of relative density-

$\sigma =\frac{\text{density of unknown object}}{\text{density of the known object}}$
