Calculate the theoretical yield and percent yield for experiments 7, 8, and 9. For experiment 9, determine the theoretical yield based on starting with 0.50g of 3-nitrobenzoic acid. Show work Acid I (experiment 7): Weight of methyl 3-nitrobenzoate = 1.9 g Acid II (experiment 8): Weight of 3-nitrobenzoic acid = 1.75 g Acid III (experiment 9): Weight of 3-nitrobenzamide = 0.30 g Experiment 7: -2.5 mL concentrated H2SO4 -1.75 mL concentrated HNO3 (16M) -2.1 mL concentrated Methyl Benzoate Experiment 8:...
