Question

The density of mercury is 13600 kgm-3. So, the relative density of mercury is A. 13.6 B. 1.36 C. 136

Answer 1

The density of water is,

$d_w=1000kgm^{-3}$

The density of mercury is,

$d_m=13600kgm^{-3}$

The relative density of mercury is the density of mercury concerning the density of water.

Thus, the relative density of mercury is,

$\begin{gathered} \frac{d_m}{d_w}=\frac{13600}{1000}_{} \\ \frac{d_m}{d_w}=13.6 \end{gathered}$

Hence, option A is the correct answer.
