calculate the entropy change with phase changes

calculate the entropy change which occurs when 36.0g of H2O vapor at 110 C is cooled, condensed to a liquid, at 100C, the liquid is converted to a solid at 0C and the solid is then cooled to -10C. For water:
Cp(vapor) = 33.6J/mol.K
Cp(liquid) = 75.2J/mol.K
Cp(solid) = 37.6J/mol.K
ΔHfusion = 6.019kJ/mol
ΔHvaporization = 40.7kJ/mol
