In the space shuttle, the CO2 that the crew exhales is removed from the air by a reaction within canisters of lithium hydroxide. On average, each astronaut exhales about 20.0 mol of CO2 daily. What volume of water will be produced when this amount of CO2 reacts with an excess of LiOH? (Hint: the density of water is about 1.oo g/mL.)
CO2(g) + 2 LiOH(s) ------> Li2CO3(aq) + H2O
360.32 mL
