lithium oxide is an effective absorber of carbon dioxide and can be used to purify air in confined areas such as space vehicles. what volume of carbon dioxide can be absorbed by 1.00 kg of lithium oxide at 25 degrees C and 1.00atm?

Question

Li2O(aq) +CO2(g) -> Li2Co3(s)

Answer 1

mols Li2O = 1000 g/molar mass Li2O
mols CO2 = mols Li2O (from the coefficients in the balanced equation)
Then use PV = nRT and convert mols CO2 to volume at the conditions listed..
