How do i calculate the percent yield of impure aspirin? I have a crude sample of 1.275, a pure sample of 0.855g and a theoretical yield of 1.326g. In my notes I wrote that percent yield of impure is actual/ theoretical x 100%. Im confused what "actual" is. is "actual" the pure .855g or the crude 1.275g?
Homework Answers
crude sample of 1.275g
pure sample = 0.855g
Theoretical yield = 1.326g
pure sample is actual yield = 0.855g
percent yield = actual yield *100/theoretical yield
= 0.855*100/1.326 = 64.45% >>>>answer
