Question

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

• A. 1830
• B. 183
• C. 18.3
• D. 1.83

Answer 1

The correct option is C 18.3

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

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

$\therefore$ Relative density of solid $r_s=\frac{\rho }{{\rho }_w}=\frac{18300}{1000}=18.3$
