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$\degree$C and 1.00 atm? Li₂O(aq) + CO₂(g) $\rightarrow$Li₂CO₃(s)

1.00 kg of Li2O can absorb 22.4 moles of CO2 (since the molar mass of Li2O is 29.88 g/mol). At 25°C and 1 atm, 1 mole of gas occupies 24.45 L. Therefore, 22.4 moles of CO2 will occupy 22.4 * 24.45 L = 819 L.
