The density of a solid is $18300 kg/m^3$. What is its relative density?

The density of water   ${\rho }_w=1000$  $kg/m^3$

Given:

Density of solid   $\rho =18300$  $kg/m^3$

$\therefore$ Relative density of solid      = $\frac{density of subs\tan ce \rho }{density of water {\rho }_w}$

Relative density of solid   = $\frac{18300}{1000}$ = 18.3 

 Relative density of solid   = 18.3
