Calculate the yield of the reaction product from the theoretically possible one if the oxidation of propanol

Calculate the yield of the reaction product from the theoretically possible one if the oxidation of propanol 1 with a mass of 7.2 g produces propionic acid with a mass of 7.4 g.

Let’s execute the solution:
1. We write down the equation according to the problem statement:
m = 7.2 g. m = 7.4 g. W -?
С3Н7ОН + CuO = H3C – CH2 – COOH + Cu + H2O – alcohol oxidation, propionic acid was obtained;
2. Calculations according to the formulas of substances:
M (C3H7OH) = 60 g / mol;
M (C3H6O2) = 74 g / mol;
Y (C3H7OH) = m / M = 7.2 / 60 = 0.12 mol.
3. Find the mass of acid, the output from the theoretically possible:
m (theoretical) C3H6O2 = Y * M = 0.12 * 74 = 8.88 g;
W = m (practical) / m (theoretical) / 100;
W = 7.4 / 8.88 * 100 = 83.33%.
Answer: The yield of propionic acid is 83.33%.
