Answer

Answer:

C. 1.16 moles

Explanation:

Step1: Calculate moles of CO₂

$n_{CO_2}=\frac{m}{M}=\frac{25.5\ g}{44.01\ g/mol}\approx0.579\ mol$

Step2: Use mole - ratio from equation

From $CO_2 + 2LiOH\rightarrow Li_2CO_3 + H_2O$, mole - ratio of $CO_2$ to $LiOH$ is 1:2. $n_{LiOH}=2\times n_{CO_2}$

Step3: Calculate moles of LiOH

$n_{LiOH}=2\times0.579\ mol = 1.158\ mol\approx1.16\ mol$
