To solve the problem of finding the volume of benzoic acid required to prepare a 93 mL buffer solution with a pH of 4.5, we will use the Henderson-Hasselbalch equation. Here are the steps to arrive at the solution: ### Step-by-Step Solution: 1. **Identify Given Values:** - pKa of benzoic acid (C6H5COOH) = 4.2 - Desired pH of the buffer = 4.5 - Total volume of buffer solution = 93 mL ...
