Below are sample questions representative of the exercises included on this worksheet and related 11.70 Percent Yield, Theoretical Yield, and Actual Yield skill assessments:

Problem 1Difficulty: Mastery

A class compares two procedures. Procedure A has 70.0% yield with very pure product; Procedure B has 92.0% apparent yield but the product is visibly wet. Which conclusion is most defensible?

AProcedure B's apparent yield may be inflated, so purity and drying data are needed before comparing true yields.

BProcedure B is definitely better because any higher percent yield is always more accurate.

CProcedure A must have a wrong balanced equation.

DProcedure B proves that wet products react more completely.

Solution & Explanation:Percent yield must be interpreted with product quality. Extra water can raise measured mass without increasing the amount of pure product.

Problem 2Difficulty: Mastery

A student chooses percent loss, (theoretical - actual) / theoretical x 100%, instead of percent yield for a reaction with theoretical yield 8.00 g and actual yield 6.40 g. Which pair of values is correct?

APercent loss is 80.0%, while percent yield is 20.0%.

BBoth percent loss and percent yield are 80.0%.

CPercent loss is 20.0%, while percent yield is 80.0%.

DPercent yield is 125%, while percent loss is 20.0%.

Solution & Explanation:The missing mass is 1.60 g, so percent loss is 1.60/8.00 x 100% = 20.0%. Percent yield is 6.40/8.00 x 100% = 80.0%.

Problem 3Difficulty: Mastery

A reaction's theoretical yield is calculated from a limiting reactant as 0.0750 mol product. The actual mass is 5.10 g and the product molar mass is 85.0 g/mol. What is the percent yield?

A80.0%

B66.7%

C125%

D6.00%

Solution & Explanation:The actual amount is 5.10 g / 85.0 g/mol = 0.0600 mol. Percent yield = 0.0600/0.0750 x 100% = 80.0%.
