Problem 1.

A reaction has a theoretical yield of 7.5 g. The student collects 4.5 g. What is the percent yield?

Show solution

4.5 ÷ 7.5 × 100 = 60%.

Problem 2.

A reaction has a theoretical yield of 15.3 g. The student collects 12.39 g. What is the percent yield?

Show solution

12.39 ÷ 15.3 × 100 = 80.98%.

Problem 3.

A reaction has a theoretical yield of 7.9 g. The student collects 7.11 g. What is the percent yield?

Show solution

7.11 ÷ 7.9 × 100 = 90%.

Problem 4.

A reaction has a theoretical yield of 6.3 g. The student collects 5.04 g. What is the percent yield?

Show solution

5.04 ÷ 6.3 × 100 = 80%.

Problem 5.

A reaction has a theoretical yield of 16.1 g. The student collects 15.62 g. What is the percent yield?

Show solution

15.62 ÷ 16.1 × 100 = 97.02%.

Problem 6.

A reaction has a theoretical yield of 4.3 g. The student collects 2.71 g. What is the percent yield?

Show solution

2.71 ÷ 4.3 × 100 = 63.02%.
