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
