In a spacecraft, the carbon dioxide exhaled by astronauts can be removed by its reaction with lithium hydroxide, LiOH, according to the following chemical equation.

CO2(g) + 2LiOH(s) --> Li2CO3(s) + H2O(l)

If 20.0 moles of CO2 is exhaled, the average amount exhaled by a person each day, how much (in grams) Li2CO3(s) is produced?
