Chlorofluorocarbons such as ccl 3 f and ccl 2 f 2 have been linked to ozone depletion in antarctica. as of 1994, these gases were found in quantities of 261 and 509 parts per trillion (10 12 ) by volume (world resources institute, world resources 1996–97). compute the molar concentration of these gases under conditions typical of (a) the mid-latitude troposphere (10°c and 1.0 atm) and (b) the antarctic stratosphere (200 k and 0.050 atm).

Some liquids can be distilled, but only at temperatures that are so high that it is impractical, or so high the compound decomposes. explain why distillation such compounds at significantly less than atmospheric pressure (some degree of vacuum) would solve this problem.
