Question:

When water is supercooled, it freezes at a temperature below 0.0oC. If 10.9 kJ of heat is released when 2.00 moles of supercooled water at 215.0oC freezes, calculate the molar enthalpy of fusion for ice at 0.0oC and 1 atm. Assume the molar heat capacities for H2O(s) and H2O(l) are 37.5 J K-1 mol-1 and 75.3 J K-1 mol-1, respectively, and are temperature independent.
