Suppose that in the synthesis of benzoic acid , a student uses 1.333 grams of magnesium , 7.122 grams of bromobenzene , and 15.933 grams of dry ice. if the mass of benzoic acid obtained were 4.66, what was the percent yield?'
To determine the percent yield of benzoic acid, you would first determine the theoretic yield.
The theoretic yield is (1.333 + 7.122 + 15.933) this equals 24.388 grams
The mass of benzoic acid obtained was 4.66 grams which is the actual yield. So to determine the percent yield, you would divide the actual yield by the theoretical (
4.66/24.388) and then multiply by 100 to give the percent yield 19.108%
