When water is supercooled, it freezes at a temperature below 0.0°C. If 10.9 KJ of heat is released when 2.00 mol of supercooled water at -15.0°C freezes, calculate the molar enthalpy of fusion for ice at 0.0°C and 1 atm. (Assume the molar heat capacities for H2O(s) and H2O(1) to be temperature independent and are 37.5 J/K mol and 75.3 J/K-mol, respectively)
