The balanced equation is: C4H6O3+C7H6O3→C9H8O4+C2H4O2.In a laboratory synthesis, a student begins with 5.00 mL of acetic anhydride (density = 1.08 g / mL) and 2.08 g of salicylic acid. Once the reaction is complete, the student collects 2.47g of aspirin.   I need to find the theoretical yield and the percent yield. I know that the Limiting reactant is C7H6O3 Follow • 4 Add comment More Report

Best Newest Oldest By: Best Newest Oldest You have to set up a stoichiometric expression to determine how much salicylic acid (SA) you should have made. Information you need to complete this.... 1) Molar mass of SA C: (12.01g) x 7= 84.07g H: (1.01g) x 6= 6.06g O: (16.00g) x 3= 48.00 --------------------------------------... 138.13g/mol salicylic acid   2) Molar mass of Aspirin C: (12.01g) x 9= 108.09 g H: (1.01g) x 8= 8.08 g O: (16.00g) x 4= 64.00 g --------------------------------------... 180.17g/mol aspirin     Since SA is your limiting reagent, the volume of Acetic anhydride is not relevant. Set up a dimensional analysis, utilizing units and formulas. (Remember to use the correct # of decimal points that your teacher requests and follow significant digit rules)   2.08g SA x 1 mol SA        x 1 mole aspirin  x   180.17 g aspirin                  138.13 g SA      1 mole SA             1 mole aspirin   Multiply across the top and divide by the bottom   Answer = theoretical yield       Then to calculate percent yield Take your actual yield (2.47 g) divide by theoretical yield from above (_____) and multiply by 100 to get a percent.     Upvote • 7 Downvote Comments • 2 More Report Report
