Question

A student isolated 15.6 g of product from a chemical reaction. She calculated that the reactions should have produced 18.4 g of product. What was the student's percent yield?
A- 84.8%

B- 15.2%

C- 95.4%

D- 45.9%

Answer 1

Answer:

The percent yield of this reaction is 84.8 % (option A is correct)

Explanation:

Step 1: Data given

The student isolated 15.6 grams of the product = the actual yield

She calculated the reaction should have produced 18.4 grams of product = the theoretical yield = 18.4 grams

Step 2: Calculate the percent yield

Percent yield = (actual yield / theoretical yield ) * 100 %

Percent yield = (15.6 grams / 18.4 grams ) * 100 %

Percent yield  = 84.8 %

The percent yield of this reaction is 84.8 % (option A is correct)
