Answer to Question #1091 in Inorganic Chemistry for Thomasina

Question #1091
One method of removing CO2 gas from a spacecraft is to allow the CO2 to react with LiOH.
How many liters of CO2 at 25.9 degrees Celcius and 751 Torr can be removed per kilogram of LiOH consumed?
Expert's answer
CO2 + 2LiOH = Li2CO3 + H2O
We have 1kg LiOH : 1000g/(7+16+1) g/mol = 1000/24 = 41.67 mol.


Thus M(CO2) = 2 M(LiOH) = 83.33 mol
m(CO2) = 83.33 mol * (12 + 2*16) g/mol = 4000 g = 4 kg.

Use the equation
pV = ν R T



p = 751 torr = 100 125.099 Pa, T = 25.9 C = 298.9 K
V = ν R T / p = 83.33 * 8.31 *298.9 /100125.099 = 2.07 m3 = 2067.2 Liters
