Percentage Yield: 

Percentage Yield Mass-mass problems give us theoretical amounts The maximum possible yield for a desired product Percentage Yield compares the theoretical amount with the actual amount obtained in an experiment

Practice Problem: 

Practice Problem The actual amount of product in a reaction is 45.0g, although a mass-mass calculation predicted 57.9g. What is the percentage yield of this product?

Practice Problem: 

Practice Problem What is the percentage yield in the following reaction if 5.50 g of hydrogen react with nitrogen to form 20.4 g of ammonia? N 2(g) + 3 H 2(g)  2NH 3(g) (Theoretical Yield)
