1. Calculate the vapor pressure of pure water (in torr) at 75.0 ^oC, given that the enthalpy of vaporization of water is 40.7 kJ mol^-1 and that the vapor pressure of pure water at 25.5 ^oC is 23.9 torr. R = 8.314 J mol^-1 K^-1.

2. The heat of fusion of water is 6.01 kJ/mol. The specific heat of liquid water is 75.3 J/mol K. How much TOTAL heat (kJ) is required for the conversion of 45.0 g of ice at 0.00C to liquid water at 10.0C? q = (SH)(Y)(DT) q = (DH)(mol) where Y = mol or g
