Grams of Lithium Carbonate Formed
Not what you're looking for?
(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.
