Percent Yield Worksheet Answer Key What is the percent yield of I 2 if the actual grams produced is 39 78 grams of I 2 from 62 55 grams of NaI and excess of all the other reactants Answer 54 Actual Yield 39 78 g of I 2 Use 62 55 grams of NaI in Stoichiometry Equation to calculate the Theoretical Yield 62 55 1 1 I K H 150 1 I K H O 2
What is my percent yield 18 5 17 2 x 100 108 c Is the answer from problem b reasonable Explain No Any yield over 100 is a violation of the Law of conservation of mass d If I do this reaction with 15 grams of sodium sulfate and get a 65 0 yield how many grams of sodium phosphate will I make The percent yield of a reaction is the ratio of the actual yield to the theoretical yield multiplied by 100 to give a percentage percent yield actual yield g theoretical yield g 100 The method used to calculate the percent yield of a reaction is illustrated in Example 4 Example 4 Novocain
