Start with 0027moles of aspirin limiting reagent going to 0027moles of salicylic acid. Putting all this together. We did not get 100 yield which should have been 2623g of aspirin.
If the percent yield in this reaction is 785 what mass of salicylic acid is required to produce 150.
The percent yield of this reaction is going to be the actual yield divided by the theoretical yield multiplied by 100. Using the molar mass of aspirin you get the number of moles of aspirin produced. EXAMPLE If the theoretical yield of aspirin is 2748 g and you obtained 247 g of aspirin what is your percent yield. Store the Aspirin in the Desi-cooler and determine the percent yield of the synthesis by taking the actual yield and dividing it by the theoretical yield determined from the original amount of Salicylic acid used.
