Determine the theoretical maximum moles of ethyl acetate, , that could be produced in this experiment. The reactant, acetic acid

kherson [118]

Answer:

0.1832 moles of ethyl acetate ( $C_{4}H_{8}O_{2}$ )

Explanation:

1. Find the balanced chemical equation:

In the production of ethyl acetate, the acetic acid $CH_{3}COOH$ reacts with ethanol to produce ethyl acetate $C_{4}H_{8}O_{2}$ and water, that is:

$CH_{3}COOH+C_{2}H_{5}OH=C_{4}H_{8}O_{2}+H_{2}O$

2. Find the theoretical maximum moles of ethyl acetate $C_{4}H_{8}O_{2}$ :

As the problem says that the acetic acid $CH_{3}COOH$ is the limiting reagent, use stoichiometry to find the moles of ethyl acetate produced:

$11gCH_{3}COOH*\frac{1molCH_{3}COOH}{60.05gCH_{3}COOH}*\frac{1molC_{4}H_{8}O_{2}}{1molCH_{3}COOH}=0.1832molesC_{4}H_{8}O_{2}$
