11. The chlorofluorocarbon CCI2F2 (Freon; MW=120.91 g/mol) was once used as a refrigerant. Cooling comes from the evaporation of the refrigerant. Calculate the mass of CCI»F2 that must evaporate in order to freeze 15.00 g of water initially at +20.0°C. The heat of vaporization, AHvap, of CCl2F2 is 34.94KJ/mol. (Hint: It will be helpful to remember the first law of thermodynamics - Energy is conserved.) Jome on
