    Density of liquid in CGS system is \[0.625\text{ }g/c{{m}^{3}}\] What is its magnitude in SI system?

    A)  \[0.625\]        

    B)  \[0.0625\]

    C)  \[0.00625\]     

    D)  \[625\]

    Correct Answer: D

    Solution :

    We know that \[density=\frac{mass}{volume}\] In CGS units \[d=0.625g/c{{m}^{3}}\] In SI units \[d=\frac{0.625\times {{10}^{-3}}kg}{{{10}^{-6}}\,{{m}^{3}}}=625kg/{{m}^{3}}\]
