**Titration Problem: Calculating Molarity of HCl Solution**

**Problem Statement:**
What is the molarity of an HCl solution if 30.5 mL of 0.500 M NaOH is required to neutralize 0.0600 L of HCl during a titration?

**Solution:**

To find the molarity of the HCl solution, use the formula derived from the concept of titration:

\[ \text{Molarity of Acid (HCl)} = \frac{\text{Molarity of Base (NaOH) × Volume of Base}}{\text{Volume of Acid (HCl)}} \]

**Given:**
- Molarity of NaOH = 0.500 M
- Volume of NaOH = 30.5 mL = 0.0305 L (convert mL to L)
- Volume of HCl = 0.0600 L

**Calculation:**

\[ \text{Molarity of HCl} = \frac{0.500 \, \text{M} \times 0.0305 \, \text{L}}{0.0600 \, \text{L}} \]

\[ \text{Molarity of HCl} = \frac{0.01525}{0.0600} \]

\[ \text{Molarity of HCl} = 0.2542 \, \text{M} \]

Thus, the molarity of the HCl solution is 0.2542 M.
