A chemist carries out this reaction in the laboratory using 4.31 grams of zinc and an excess of sulfur: Zn + S$\rightarrow$ZnS
From the balanced equation,she calculates that she should obtain 6.41 grams of zinc sulfide.However,she isolates only 5.01 grams of product.What is her percent yield for this reaction?

Question

Quizplus · Accepted Answer

Percent yield is calculated as (actual yield/theoretical yield) x 100. Here, (5.01 g / 6.41 g) x 100 = 78.2%.
