Certain salts of benzoic acid have been used as food additives for decades. The potassium salt of benzoic acid, potassium benzoate, can be made by the action of potassium permanganate on toluene according to the following reaction (unbalanced): C7H8 + KMnO4 = KC7H5O2 + MnO2 + KOH + H2O If the yield of potassium benzoate cannot realistically be expected to be more than 69.50%, what is the minimum number of grams of toluene needed to achieve this yield while producing 10.00 g of KC7H5O2?
