Webwhere ΔH°fus is the enthalpy of fusion and ΔH°vap,298 is the enthalpy of vaporization at 298 K. Since we have the enthalpy of formation of H 2 O(1) and H 2 O(g), we can use the following equation to calculate ΔH°fus: ΔH°fus = ΔH°f(H 2 O(1)) - ΔH°f(H 2 O(g)) ΔH°fus = -285.830 kJ/mol - (-241.818 kJ/mol) = -44.012 kJ/mol WebHeat of formation of H2O is - 188 kJ/mol and H2O2 is 286 kJ/mol.
