How many grams of acetic acid can be obtained by oxidizing 22 grams of acetaldehyde

How many grams of acetic acid can be obtained by oxidizing 22 grams of acetaldehyde if the practical product yield is -75%

To solve, we write down the equation of the process:

CH3 – СОН + Ag2O = CH3 – COOH + 2Ag – oxidation of aldehyde with silver oxide, acetic acid and silver are released;
We make calculations:
M (C2H4O) = 44 g / mol;

M (C2H4O2) = 60 g / mol;

Y (C2H4O) = m / M = 22/44 = 0.5 mol.

Find the mass of the product:
m (C2H4O2) = Y * M = 0.5 * 60 = 30 g (theoretical weight);

W = m (practical) / m (theoretical) * 100;

m (C2H4O2) = 30 * 0.75 = 22.5 g (practical weight).

Answer: the mass of acetic acid is 22.5 g
