SOLVED:The chlorofluorocarbon refrigerant Freon-12, CCl2  F2, was banned in 1995 to help protect the ozone layer. Most new air conditioning units now use the refrigerant tetrafluoroethane, CF3 CH2  F. The enthalpy of vaporization of Freon-12 is 155  J ·g^-1 and that of tetrafluoroethane is 215.9  J ·g^-1. Estimate the number of grams of Freon-12 that must be vaporized to freeze a tray of 16 one-ounce (1 oz=28  g) ice cubes with the water initially at 18^∘ C. How many grams of tetrafluoroethane a
