About 921 grams of carbon dioxide will react woth 1.00 kg of lithium hydroxide.
Explanation:
Start with the equation for the reaction:
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
So the ratio of lithium hydroxide to the carbon dioxide it reacts with is
