In the International Space Station (ISS), the carbon dioxide that the crew exhales is removed from the air by a reaction within canisters of lithium hydroxide. On average, each astronaut exhales 20.0 mol of carbon dioxide daily. What mass of lithium hydroxide will react completely with this amount of carbon dioxide?
CO2(g) + 2 LiOH(s) ------> Li2CO3(aq) + H2O
CO2(g) + 2 LiOH(s) ------> Li2CO3(aq) + H2O
1 mol CO2 in the equation requires 2 mol LiOH so 20.0 for each astronaut will require 40 mols LiOH. Right.
