One method of removing CO2(g) from a spacecraft is to allow the CO2 to react with LiOH. What volume, in liters, of CO2(g) at 26.0°C and 793 Torr can be removed per kilogram of LiOH consumed?
2LiOH(s) + CO2(g) -> Li2CO3(s) + H2O(l)
Use stoichiometry to convert 1 kg LiOH to liters CO2 at STP. Convert liters CO2 at STP to mols, then use PV=nRT to adjust to 26 C and 793 Torr. Post your work if you get stuck.
