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

JamiaJamia 2010

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}} $
