    The specific heat of \[Ar\] at constant volume is \[0.075\text{ }k{{g}^{-1}}{{K}^{-1}}.\] Calculate the atomic weight \[~\left( R=2\text{ }cal\text{ }mo{{l}^{-1}}{{K}^{-1}} \right)\]

    A) 40 

    B) 40.4  

    C) 40.2  

    D) 40.80

    Correct Answer: A

    Solution :

    [a] \[M=\frac{{{C}_{V}}}{{{S}_{V}}}=\frac{\frac{3\times 2}{2}}{0.075}=40\therefore {{C}_{V}}=\frac{3}{2}R\]
