In a lab, a scientist calculate he should produce 12.3 grams of product in his experiment. When he is finished collecting his product it weighs 11.0 grams. What is his percent yield?

Answer:
Option D.
Explanation:
Percentage yield = Actual yield / Theoretical yield * 100%
Actual yield = 11.0 grams
Theoretical yield = 12.3 grams
Percentage yield = 11.0 / 12.3 * 100
Percentage yield = 89.43%
