Question

The value of density of mercury in CGS system is $13.56$ $g{cm}^{-3}$. Its value in SI system is:

• A. $135.6$ $kg{m}^{-3}$
• B. $13.56$ $kg{m}^{-3}$
• C. $1.356$ $kg{m}^{-3}$
• D. $13560$ $kg{m}^{-3}$

Answer 1

Answer: (D)

$13560$ $kg{m}^{-3}$

$13.56g/c{m}^3=13.56\times {10}^{-3}/({10}^{-2}{)}^3=13.56\times 1000=13560kg/m^3$
