The aspirin from the above experiment was not pure. 121.2 g of solid was obtained, but analysis showed that only 109.2g of it was aspirin. Calculate the percent purity of the product. ... In this lesson, we will consider how to calculate the percent yield from a reaction and the percent purity of the product obtained.

18. Repeat the titration with the other portion of the purified aspirin, taking care to record in your notebook the initial and final reading of the buret, and the weight of the sample titrated. Leave space in your notebook to calculate the number of grams of aspirin in the sample and the percent purity of these samples.

In order to calculate the theoretical yield, ... In the laboratory, the percent yield has the practical aspect of telling you how successful was your synthesis scheme. A low percentage yield means that the conditions were not optimal and could be improved. Perhaps there are competing reactions occurring or some of the...

First let's calculate the formula weight so that we can then calculate how many moles .070 g of the substance is. ... For example, every molecule of ammonia is NH3 and 17.03 g of ammonia always has 14.01 g of N and 3.02 g of H. Therefore we can now calculate the percent composition of each element in ammonia:
