Chlorofluorocarbons such as `C Cl_(3)F` (molecular mass=137.5) and `C Cl_(2)F_(2)` (molecular mass=121) have been linked to ozone depletion in Antarctica. A research reported that the concentration of these gases are 240 and 800 parts per trillion `(10^(12))`, by volume respectively. what are the concentrations of these gases (in moles per litre). under conditions typical of Antarctic stratosphere (200K and 0.05 atm)? (R=0.08L-atm/K-mol)
