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(8)
+
2 LiOHs
-
Li2CO3(2)
+
H2O(1)
If a typical cannister of LiOH contains 750.0 g, how many hours will
it last for one person before it has to be replaced?
