Chapter 6.5, Problem 6.9P

Lithium oxide was used aboard the space shuttle to remove water from the air supply. If 80.0 kg of water is to be removed and 65 kg of Li₂O is available, which reactant is limiting? How many kilograms of the excess reactant remain?

${\text{Li}}_{\text{2}}\text{O}(s)+{\text{H}}_{\text{2}}\text{O}(g)\stackrel{}{\to }2\text{LiOH}(s)$
