Using stoichiometry a student determines that 33.3 grams of PbCrO4 will be produced during a reaction. After performing the experiment, 27.2 grams of PbCrO4 are collected. What is the percent yield of the reaction?

81.7% is percent yield of the reaction

Explanation:

Percent yield of a reaction is defined as 100 times the ratio between actual yield and theoretical yield of the reaction. The theoretical yield is obtained using stoichiometry.

In the problem, theoretical yield was 33.3g of PbCrO₄ and the yield obtained was of 27.2g of PbCrO₄. That means percent yield is:

27.2g / 33.3g * 100

= 81.7% is percent yield of the reaction
