$\underline\bold\red{\huge{ANSWER : }}$

⭐ The relative density (R. D.) of a substance is defined as the ratio of the density of that substance to the density of water at 4°C.

⭐ Relative density is also called as specific
gravity.

⭐ Relative Density Of Mercury
$= \frac{13.6 \times {10}^{3} }{1000}$

$= \frac{13.6 \times {10}^{3} }{ {10}^{3} }$

$= 13.6 \: \: (answer)$
