The density of a liquid in the CGS system is 0.625 $0.625 g {cm}^{- 3}$ . What is its magnitude in SI system?

Options:

Answer:

Solution:

$N_{1} U_{1} = N_{2} U_{2}$ $N_{1} [M_{1} L_{1}^{- 3}] = N_{2} [M_{2} L_{2}^{- 3}]$
∴ $N_{2} = N_{1} [\frac{M_{1}}{M_{2}}] \times {[\frac{L_{1}}{L_{2}}]}^{- 3}$ $= 0.625 [\frac{1 g}{1 k g}] \times {[\frac{1 c m}{1 m}]}^{- 3}$ $= 0.625 \times 10^{- 3} \times 10^{6} = 625$
