Compounds like CCl2F2 are known as chlorofluorocarbons, or CFCs. These compounds were once widely used as refrigerants but are now being replaced by compounds that are believed to be less harmful to the environment. The heat of vaporization of CCl2F2 is 289 J/g. How many grams of this substance must evaporate to freeze 201 g of water initially at 22 oC. (The heat of fusion of water is 334 J/g; the specific heat of water is 4.18 J/g-K.)
