Question

The relative density of silver is $10.8$. The density of water $1\times {10}^{3}kg.m^{-3}$. What is the density of silver?

• A. $1\times {10}^{3}kg.m^{-3}$
• B. $10.8\times {10}^{3}kg.m^{-3}$
• C. $108\times {10}^{3}kg.m^{-3}$
• D. $54\times {10}^{3}kg.m^{-3}$

Answer 1

The correct option is B $10.8\times {10}^{3}kg.m^{-3}$

Relative density $=\frac{\text{Actual density}}{\text{Density}}$

$\Rightarrow$$10.8=\frac{\text{Density of silver}}{{10}^3}$

$\Rightarrow {\rho }_{\text{silver}}=10.8\times {10}^{3}kg.m^{-3}$
