Answer:
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
