how to find percent yield of aspirin. Calculate the theoretical yield of aspirin to be obtained in experiment 20 grams of salicylic acid and 50 mL of acetic anhydride density 108gmL. The combined mass of both reagents and containers is 25598 g.

How to calculate the percent yield of a chemical reaction. So what if the sodium hydroxide is not in excess at least we dont know if it is. Consider a 352-g sample of CaCO 3 9987 pure in a flask and a 1000 mL sample of vinegar 5 acidity in a graduated cylinder.
The crude product was then dissolved in 5ml of warmed via water bath 100 ethanol.
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. Molar Mass of C 12 grams Molar Mass of H 1 grams. Calculate the percent yield of aspirin if 452 grams of aspirin is produced when 495 grams of salicylic acid is reacted with excess acetic anhydride. 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.
