You calculate the theoretical yield of aspirin, and then you use your actual yield to calculate the percent yield.


Here's how to calculate the theoretical yield of aspirin.

And here's how you calculate percent yield.


If the theoretical yield of aspirin is 2.748 g and you obtained 2.47 g of aspirin, what is your percent yield?


#"Percent yield" = "actual yield"/"theoretical yield" × "100 %" = (2.47 color(red)(cancel(color(black)("g"))))/(2.748 color(red)(cancel(color(black)("g")))) × "100 %" = "89.9 %"#
