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?

How many moles of benzaldehyde (density d = 1.04 g/ml), (molecular weight mw = 106.12 g/mol) are required to react with 1.0 ml of acetone: (density d = 0.79 g/ml), (molecular weight mw = 58.08 g/mol)? 6. What is approximate theoretical yield for problem # 5 if you obtained 2.1 grams of dibenzylidene acetone (mw = 234.29 g/mol)?

i dont understand why the molecular weight i calculated
(42.012 g/mol) for my unknown liquid (acetone) is less than the
actual molecular weight (58.08 g/mol). what errors could i have
made in my lab that would account for the difference.
