One of the challenges astronauts face is in space travel is the build-up of carbon dioxide in their spacecraft. The average human exhales about 42.0 g of carbon dioxide per hour. One method to remove the excess carbon dioxide from the air is using solid lithium hydroxide:
CO2(g) + 2 LiOH(s) → Li2CO3(2) + H2O(l)
If a typical canister of LiOH contains 750.0 g, how many hours will it lasts for one person before it has to be replaced?
