Calculate the pH of a 0.01 M solution of benzoic acid, the `K_a` being `7.3xx10^(-5)`

Explanation

To calculate the pH of a 0.01 M solution of benzoic acid (C6H5COOH) with a given \( K_a \) of \( 7.3 \times 10^{-5} \), we can follow these steps:

### Step 1: Write the dissociation equation
Benzoic acid dissociates in water as follows:
\[ \text{C}_6\text{H}_5\text{COOH} \rightleftharpoons \text{C}_6\text{H}_5\text{COO}^- + \text{H}^+ \]
