C7H6O3(s) + C4H6O3(aq) --> C9H8O4(s) + C2H4O2(aq)
If you don't know how to balance a chemical equation yet, here is a website to tell you how: Balancing Chemical Equations
Next, we used the mass of the starting salicylic acid to determine the theoretical amount of the acetylsalicylic acid formed, and got 6.7110g C9H8O4
Lastly, we determined the percent yield of the reaction by using this equation:

Here is a website explaining how to calculate this: Percent Yield
When I used the above formula to calculate the percent yield of the aspirin lab, I came up with 77.179%.
Thanks for this post Carly. I really enjoyed how you walked through all the steps of what you used to find the percent yield. It was very helpful that you also attached links when you recognized some people may run into problems. I also had that answer for the percent yield, so we must both be understanding this concept! Thanks again for this post!
ReplyDeleteCarly, this was a very good walkthrough of the assignment! It made a lot of sense and was helpful to me because I can use the links to review the concept. Very good post, thank you!
