Question

Density of mercury is 13.6 g $c{m}^{-3}$, then the value in MKS system is _____

Answer 1

Density of mercury $\rho =13.6g$ $c{m}^{-3}$

We know, $1g=\frac{1}{1000}kg$

Also $1cm=\frac{1}{100}m$

In SI unit, $\rho =13.6\times \frac{1}{1000}kg$ $\times (100{)}^3{m}^{-3}$

$⟹$ $\rho =13600kg{m}^{-3}$
