Specific Heat capacity and Molar specific Heat capacity

Chaitanya asked:

“how to calculate molar the heat capacity of a gas
given cp and cv of the gas?”

 

Answer:

Specific heat capacity of a substance is the quantity of heat required to raise the temperature of 1g of that substance through 1oC. It can be measured at constant pressure (Cp) and at constant volume (Cv).

Molar heat capacity of a substance is the quantity of heat required to raise the temperature of 1 mole of the substance by 1oC.

Molar heat capacity = Specific heat capacity × Molecular weight,

i.e.,

Cv = cv × M and Cp = cp × M.
