7.4 Theoretical and Percent Yield 10. A chemist carries out the following reaction: CH + Br2 → C.H.Br + HBr (2 points each) a. If he reacts 14.2 grams of CoHs with an excess of Brz, what is the theoretical yield of CeHsBr? 14:29 CGHE X Imol CGHE & Imol 78. 112g C6H6 - b. If he collected 16.3 grams of CHsBr after finishing his experiment, what is his percent yield?
an experiment only formed 14 g of product (actual yield), thus the percent yield of product for that experiment is 1.4/2.0x100 - 70% % yield actual yield theoretical Wald X 100 You can rearrange this equation to calculate the actual yield if given the % and theoretical yields, or the theoretical yield if given the % and actual yields. Let's Practice: 1. Answer the following questions based on the reaction below (5pts) 2 NaCl + Mg0 Na2O + MgCl2 What...

10. Calculate the theoretical yield of aspirin using 4.00 g of salicylic acid as the starting material. Assume acetic anhydride is in excess. (Hint: from the mass of salicylic acid acid use, how many moles of salycilic acid are present intitially? What is the salycilic acid : acetylsalicylic acid molar ratio? How many moles of acetylsalicylic acid are formed assuming 100% yield? Based on this abount of moles, how many grams of acetylsalicylic acid are formed? (this is the theoretical...

a. What is the theoretical yield of oxygen if 125 g of H2O2 is decomposed? (10 points) 25+ Imol = 3.67 x 2mol on 134.01 = 3.67 2.0 = zmol H2O2 Imol What is the percent yield if 27.4 grams of O2 are collected? (10 points)
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?
If you started this experiment with 4.75 grams of tea leaves, what would the theoretical yield of caffeine be assuming the mass percent of caffeine in tea leaves is the same as in Question 5? The mass percent of tea leaves in Question 5 was 5%.
