I just need problem 7. Thanks!

An organic chemistry laboratory student used 5.65 grams of methyl benzoate to prepare Methyl-m-nitrobenzoate according to the experimental procedure. The mass of the student's crude product was 6.42grams and the mass of the student's purified product was 5.33 grams. Answer the questions that follow. Question 7 1 pts Under ideal conditions, what is the theoretical yield of methyl-m-nitrobenzoate that could be prepared by the student? Enter your numerical answer below with the correct number of significant figures. Question 8 1 pts What is the percent yield of the student's crude product? Enter your numerical answer below with the correct number of significant figures. Question 9 1 pts What is the percent yield of the student's purified product? Enter your numerical answer below with the correct number of significant figures
