how to calculate percent yield of aspirin synthesis. EXAMPLE If the theoretical yield of aspirin is 2748 g and you obtained 247 g of aspirin what is your percent yield. So 0725 moles gives 0725 moles of aspirin 0725 moles of aspirin 0725 180 g 1305 g So the calculated mass of the reaction is 1305 g Step 4.

There are contaminants present in the form of your starting materials and is probably the result of not letting a reaction continue to completion or not rinsing correctly. Aspirin Synthesis and Analysis. The amount of crude aspirin synthesized was 3029 grams and the amount of pure aspirin synthesized was 2169.

A percent yield of 90.

Percent yield mass of dried recrystallised aspirin expected mass of aspirin x 100 Percent yield is the amount of substance we have obtained in total in the. It is never good to have a experimental yield larger than a theoretical yield. Lab 3 and 4. Aspirin Synthesis and Analysis.
