Question

The relative density of lead is $\mathrm{11.3.}$ Its density is $gc{m}^{-3}$ or $kg{m}^{-3}$

• A. $11.3$ or $11.3$
• B. $11.3$ or $113$
• C. $113$ or $1130$
• D. $11.3$ or $11300$

Answer 1

Answer: (D)

Relative density of lead
$=\frac{\text{ density of lead }}{\text{ density of water }}\Rightarrow 11.3=\frac{\text{ density of lead }}{1gc{m}^{-3}\text{or }1000kg{m}^{-3}}$
$\Rightarrow$ density of lead $=11.3gc{m}^{-3}$ or $11300kg{m}^{-3}$
