Lithium hydroxide is used in the space program to remove carbon dioxide (frin respiration) in spacecraft. Specifically, lithium hydroxide, LiOH reacts with carbon dioxide, CO2 to form lithium carbonate Li2Co3, and water. 2 liOH + Co2 Li2Co3+ H2O. What mass of CO2 can be absorbed by 36 g of LiOH?
Refer to the balanced equation.
mols LiOH = grams/molar mass
mols CO2 = 1/2 x mols LiOH (from the equation which is 2:1)
g CO2 = mols x molar mass.
