how do you find the percentage yield of something? i made 0.33g of aspirin before recrystallisation 0.12g of aspirin after recrystallisation I used 4cm3 of ethanoic anhydride 2.0g of 2-hydroxybenzenecarboxylic acid
what is my theoretical yield, actual yield and percentage yield?

If your reaction is perfect you get 100% yield. You work this out from the moles of the limiting reagent used ==> moles of product ==> mass of product. actual yield is the mass of product percentage yield is (actual/theoretical)*100
Your actual yield is 0.12g Your TY is calculated using the moles of 2-hydroxybenzenoic acid. As the molar ratio of the acid to aspirin is 1:1. You assume you form 2g if aspirin. Using this mass you calculate moles: moles=mass/mr
Your actual yield is 0.12g Your TY is calculated using the moles of 2-hydroxybenzenoic acid. As the molar ratio of the acid to aspirin is 1:1. You assume you form 2g if aspirin. Using this mass you calculate moles: moles=mass/mr

Then calculate PY=AT/TY
How about if i'm trying to find the percentage yield of the aspirin before recrystallisation
