how much heat is released in the conversion of 1.00 L of steam at 21.9 atm and 200 C(temperature) to ice at -6C(temperature) and 1 atm?

Given:
enthalpy of fusion(H2O)=6.01kJ/mol
enthalpy of vaporization(H2O)=40.66kJ/mol
Cp(s)(crystalline H2O)=38.02J(K*mol)
Cp(l)(liquid H2O)=75.35J/k*mol
Cp(g)(H2O gas)=33.60J/K*mol
