Convert 100 g salicylic acid (SA) to moles. moles = grams/molar mass
Using the coefficients in the balanced equation, convert moles SA to moles of the product. (The ratio is 1:1).
Now convert moles aspirin to grams aspirin. grams = moles x molar mass. This is the theoretical yield.
% yield = (actual yield/theoretical yield)*100
actual yield is 50.0 g from the problem. Theoretical yield is from your calculations.
thank you! :)
