Question

The relative density of silver is $10.8$. Its density is $X\times {10}^{3}kg{m}^{-3}$. Find X.

• A. $10.0$
• B. $11.8$
• C. $10.8$
• D. $2.0$

Answer 1

The correct option is C $10.8$

$RD=\frac{densityofsilver}{densityofwater}$
$10.8=\frac{densityofsilver}{1000kg{m}^{-3}}$
$\Rightarrow densityofsilver=10.8\times {10}^{3}kg{m}^{-3}$

comparing it with $X\times {10}^{3}kg{m}^{-3}$, $X=10.8$
