I need help with calculating the percent yield of an experiment. 1.0 g of p-aminobenzoic acid (MW=137.14 g/mol) was mixed with 10.0 mL of absolute ethanol (MW=46.07 g/mol) and after solid dissoved 1.0 mL of conc. sulfuric acid was added (MW=98.07 g/mol). The crude product of benzocaine (MW=165.19 g/mol) weighed 2.289 grams. What is the theoretical yield? What is the percent yield?
