Hi Kasini,

Molar heat capacity is usually given in kJ/molK which basically means how much energy you need to raise the temperature of 1 mole of substance by 1K.

The molar heat capacity of water at constant pressure is 75 J K^−1 mol^−1

Feel free to ask doubts in the Comment Section.

I hope this information helps you.

Good Luck!

Hello,

The molar heat capacity of a substance, which may be denoted by Cm, is the heat capacity C of a sample of the substance, divided by the amount (moles) n of the substance in the sample. The molar heat capacity of water at constant pressure, Cp  is 75.38 J K^−1 mol^ −1

Hope this helps!
