Lithium oxide ( $\mathrm{Li}_2 \mathrm{O}$; molar mass $=30 \mathrm{~g} \mathrm{~mol}^{-1}$ ) is used in space shuttles to remove water vapour according to the following reaction $\mathrm{Li}_2 \mathrm{O}_{(\mathrm{s})}+\mathrm{H}_2 \mathrm{O}(\mathrm{~g}) \rightarrow 2 \mathrm{LiOH}_{(\mathrm{s})}$ If 60 kg of water and 45 kg of $\mathrm{Li}_2 \mathrm{O}$ are present in a shuttle I. water will be removed completely II. $\mathrm{Li}_2 \mathrm{O}$ will be the limiting reagent III. 100 kg of $\mathrm{Li}_2 \mathrm{O}$ will be required to completely remove the water present IV. 27 kg of water will remain in the shuttle at the end of the reaction
