        Molar heat capacity of ethanol is\[110.4\text{ }J{{K}^{-1}}\]. Its specific heat capacity is

    A)  2.4                                        

    B)  55.2

    C)  5.078                                   

    D)  110.4

    Correct Answer: A

    Solution :

                    Specific heat capacity\[=\frac{Molar\text{ }heat\text{ }capacity}{molar\text{ }mass}\]\[=\frac{110.4\,J{{K}^{-1}}}{46}\] (\[\because \]Molar mass of ethanol = 46)\[=2.4\text{ }J{{K}^{-1}}mo{{l}^{-1}}\]
