Before going to lab, a student read in his lab manual that the percent yield for a difficult reaction to be studied was likely to be only 30.% of the theoretical yield. The student's prelab stoichiometric calculations predict that the theoretical yield should be 25.00 g. What is the student's actual yield likely to be?
Homework Answers
Theoritical yiled= 25.00grams
30% of the theoritical yield= 25.00x30/100=7.5
Percent yield= 7.5%
percent yiled= actual yield/theoritical yield x 100
actual yield= percent yiledxtheoritical yiled/100 = 7.5x25.00/100=1.875 grams
actual yiled= 1.875 grams
