In a spacecraft the carbon dioxide exhaled by astronaut can be removed by the reaction with Lithium Hydroxide, LiOH according to the following;

𝐢𝑂2 (𝑔)+𝐿𝐼𝑂𝐻 (𝑔)→𝐿𝑖𝑂𝐻 (𝑠)+𝐻2𝑂 (𝑙)
How many moles of Lithium hydroxide are required to react with 30 mol of CO2, the average exhaled by a person each day.

2 answers

Your equation is not right. Not the right products and not balanced.
CO2(g) + 2LiOH(s) ==> Li2CO3(s) + H2O(l)
The equation tell you 1 mol CO2 needs 2 mols LiOH; therefore, 30 moles CO2 will need ..........moles LiOH.
50 moles
