How many kilograms of ethanic acid can be obtained by oxidizing 9.9 kg of ethanal if the yield of the reaction product is 85%?

Let’s execute the solution:

In accordance with the condition of the problem, we write:
СН3СОН + Ag2O = CH3COOH + 2Ag – oxidation of ethanal with silver oxide, ethanic acid was obtained;

Calculations:
M (C2H4O) = 44 g / mol

M (CH3COOH) = 60 g / mol

Determine the amount of the original substance:
Y (CH3COOH) = m / M = 9900/44 = 225 mol

Y (CH3COOH) = 225 mol since the amount of substances according to the equation is 1 mol

Find the mass of the product:
m (CH3COOH) = Y * M = 225 * 60 = 13500 g (theoretical weight).

m (CH3COOH) = 0.85 * 13500 = 11475 g = 11 kg 475 g (practical weight).

Answer: the mass of ethanic acid is 11 kg 475 g
