About 921 grams of carbon dioxide will react woth 1.00 kg of lithium hydroxide.


Start with the equation for the reaction:

#2 "LiOH"+"CO"_2 \rightarrow "Li"_2"CO"_3+"H"_2"O"#

So one mole of lithium hydroxide reacts with one-half mole of carbon dioxide.

By adding up atomic masses we find that one mole of lithium hydroxide weighs about #23.9# grams and one mole of carbon dioxidecweighs about #44.0# grams.

So the ratio of lithium hydroxide to the carbon dioxide it reacts with is #23.9# grams of lithium hydroxide to #22.0# grams of carbon dioxide. Then #1.00# kg #=1.00×10^3# grams of lithium will react with:

#1.00×10^3"g LiOH"×(22.0 "g CO"_2)/(23.9 "g LiOH")=9.21×10^2"g CO"_2#
