What is the mass of acetic acid propyl ester formed during the interaction of 120 g.

What is the mass of acetic acid propyl ester formed during the interaction of 120 g. acetic acid and 120g. propyl alcohol, if the product yield was 75% of the theoretically possible.

Let’s execute the solution:

In accordance with the condition of the problem, we will write the data:

CH3COOH + C3H7OH = CH3COO – C3H7 + H2O – esterification, the propyl ester of acetic acid was obtained.

Calculations:
M (CH3COOH) = 60 g / mol;

M (C3H7OH) = 60 g / mol;

M (ether) = 102 g / mol;

Y (CH3COOH) = m / M = 120/60 = 2 mol;

Y (C3H7OH) = m / M = 120/60 = 2 mol;

Y (ester) = 2 mol since the amount of substances according to the equation is 1 mol.

Find the mass of the product:
m (word of ether) = Y * M = 2 * 102 = 204 g
Answer: the mass of propionic ester is 204 g
