Challenge Problems

Push your limits with challenges.

Question 1

A chemical reaction has a theoretical yield of 200 grams, yet the actual yield is 180 grams after purification. What is the percent yield?

💡 Hint: Set up the division carefully before multiplying by 100.

Question 2

In an industrial process, a chemical reaction produced a theoretical yield of 100 kilograms of product, but due to mishandling, only 85 kilograms was achieved. Calculate the percent yield and discuss potential reasons for this loss.

💡 Hint: Consider each step in the process of obtaining the product from reactants.
