Answer:
The molar heat capacity of water 75.24 J/mol °C.
Explanation:
Specific heat is defined as amount of energy required to raise by the temperature of 1 g of substance by 1 degree Celsius.
Molar eat capacity as amount of energy required to raise by the temperature of 1 mole of substance by 1 degree Celsius.
Specific heat and molar heat capacities can be written:
Molar heat capacity = Specific heat × Molar mass of the substance
Specific heat of water = 4.18 J/g °C
Molar mass of water = 18 g/mol
Molar heat capacity of the water :

The molar heat capacity of water 75.24 J/mol °C.
