Part 1) How much energy does it take to boil 160.0g water? The heat vaporization for water: 40.7 kJ/mol, heat of fusion: 6.02kJ/mol.

Part 2) Water at 0 degrees C was placed inside a vessel maintained at low pressure by a vacuum pump. After some of the water evaporated, the remainder froze. If 1.2g of water evaporated, how much ice was obtained? Use the heats of vaporization and fusion from the first problem.
