WebThe units for the molar heat of fusion are kilojoules per mole (kJ/mol). Sometimes, the unit J/g is used. In that case, the term heat of fusion is used, with the word 'molar' being eliminated. See Example #3 below. The molar heat of fusion for water is 6.02 kJ/mol. As you go around the Internet, you will see other values used.
