A typical aspirin tablet contains 324 mg of aspirin (acetylsalicylic acid, C9H8O4), a monoprotic acid having Ka=3.0×10?4.
If you dissolve 4 aspirin tablets in a 340mL glass of water, what is the pH of the solution and the percent dissociation?
Understand how to find the pH which =2.62
How do I find the % dissociation from there?
