Question

The density of mercury is $13600kg{m}^{-3}$. Its value in CGS system will be

• A. $13.6gc{m}^{-3}$
• B. $1360gc{m}^{-3}$
• C. $136gc{m}^{-3}$
• D. $1.36gc{m}^{-3}$

Answer 1

Answer: (A)

$13600kg{m}^{-3}=13600\times 1000g\times (100cm{)}^{-3}$
$=\frac{136\times 10^5}{10^6}gc{m}^{-3}=13.6gc{m}^{-3}$
