Answer:

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

Explanation:

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

And here's how you calculate percent yield.

EXAMPLE

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

Solution

#"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 %"#
