Determine the numbers of grams of lithium hydroxide are needed per astronaut per day?
A person exhales about 5.8 x 102L of carbon dioxide per day (at STP). The carbon dioxide exhaled by an astronaut is absorbed from the air of a space capsule by reaction with lithium hydroxide, LiOH.
2LiOH(s) + CO2(g) -> Li2CO3(s) + H2O (l)
