how much heat is released when 105 g of stem at 100.0*c is cooled to ice at -15.0*c? The enthalpy of vaporization of water is 40.67 kj/mol, the enthalpy of fusion for water is 6.01 kj/mol, the molar heat capacity of liquid water is 75.4 kj/(mol x *c), and the molar heat capacity if ice is 36.4 kj/(mol x /*c)
