Question

The relative density of silver is $\mathrm{10.8.}$ The density of water is $1000kg{m}^{-3}$. The density of silver is

• A. 10.8 kg/m³
• B. 10.8 ​ kg/m³
• C. 10.8 10 kg/m³
• D. None of these

Answer 1

The correct option is B

10.8 ​ kg/m³

Relative density is defined as the ratio of the density of a substance to the density of water at 4-degree Celsius.
So, $\frac{\text{Density of silver}}{\text{Density of water}}=10.8$
$\Rightarrow \frac{\text{Density of silver}}{1000}=10.8$
Thus the density of silver $=10.8\times {10}^{3}kg{m}^{-3}$
