Grams of Lithium Carbonate Formed

(a) Aqueous lithium hydroxide solution is used to purify air in spacecrafts and
submarines because it absorbs carbon dioxide according to the equation:
2LiOH(aq) + CO2(g) -> Li2CO3(aq) + H2O(l)

The pressure of CO2 in a cabin with a volume of 2.4 x 105 L is 7.9 x 10-3 atm at
312 K. A solution of LiOH of negligible volume is introduced into the cabin and
the pressure of CO2 is reduced to 1.2 x 10-4 atm. How many grams of lithium
carbonate are formed by this process?

b) Chlorofluorocarbon (CFC) gases and volatile liquids sold commercially as Freons
are still used in refrigeration units. A chemist found that a certain amount of a
CFC gas required 186 seconds to effuse through a porous plug when the pressure
was held constant. The same amount of carbon dioxide required 112 seconds.
Calculate the molar mass of the CFC.
