Question

Relative density of silver is $10.8$. If the density of water is ${10}^3{\text{kg/m}}^3$, find the density of silver.

• A. $10.8\times {10}^5{\text{kg/m}}^3$
• B. $10.8\times {10}^4{\text{kg/m}}^3$
• C. $10.8\times {10}^2{\text{kg/m}}^3$
• D. $10.8\times {10}^3{\text{kg/m}}^3$

Answer 1

The correct option is D $10.8\times {10}^3{\text{kg/m}}^3$

We know that,

$\text{Relative density}=\frac{\text{Density of substance}}{\text{Density of water}}$

$\Rightarrow \text{Density of substance}=\text{Relative density}\times \text{Density of water}$

$\Rightarrow \text{Density of substance}=10.8\times {10}^3{\text{kg/m}}^3$
