ANSWER
[tex]\text{ }\frac{2\text{ moles of LiOH}}{1\text{ mole of CO}_2}\text{ -------- Option A}[/tex]
EXPLANATION
To determine the ratio of LiOH to CO2, follow the steps below
Step 1: Write the balanced equation of the reaction
[tex]\text{ 2LiOH + CO}_2\rightarrow\text{ Li}_2CO_3\text{ + H}_2O[/tex]
From the above reaction, you will see that 2 moles of LiOH react with 1 mole of CO2
Hence, the coefficient of LiOH in the reaction is 2, and the coefficient of CO2 is 1
Step 2: Find the mole ratio of LiOH to CO2
[tex]\text{ Mole ratio = }\frac{2\text{ moles of LiOH}}{1\text{ mole of CO}_2}[/tex]
