Solution: Toluene, C6H5CH3, is oxidized by air under carefully controlled conditions to benzoic acid, C6H5CO2H, which is used to prepare the food preservative sodium benzoate, C 6H5CO2Na. What is the percent yield of a reaction that converts 1.000 kg of toluene to 1.21 kg of benzoic acid?
2C6H5CH3 + 3O2 ⟶ 2C6H5CO2H + 2H2O

Problem

Toluene, C6H5CH3, is oxidized by air under carefully controlled conditions to benzoic acid, C6H5CO2H, which is used to prepare the food preservative sodium benzoate, C 6H5CO2Na. What is the percent yield of a reaction that converts 1.000 kg of toluene to 1.21 kg of benzoic acid?
2C6H5CH3 + 3O2 ⟶ 2C6H5CO2H + 2H2O

Solution

Recall the formula for percent yield:

Actual yield is the given actual mass of benzoic acid produced from the reaction:

Actual yield = 1.21 kg toluene

Calculate the theoretical yield (assuming all of the 1.000 kg of toluene is converted to benzoic acid).

Balanced reaction: 2 C6H5CH3 + 3 O2⟶ 2 C6H5CO2H + 2 H2O
