### Calculation of pH for Strong Acid Solutions

**Question: Calculate the pH of each of the following strong acid solutions.**

### Part A
- **Situation:** 0.320 g of HClO₃ in 2.40 L of solution.
- **Requested:** Express the pH of the solution to three decimal places.
- **Student Response:** pH = 1.58 × 10⁻³
- **Feedback:** Incorrect; please try again. Four attempts remaining.

### Part C
- **Situation:** 15.00 mL of 1.70 M HCl diluted to 0.560 L.
- **Requested:** Express the pH of the solution to three decimal places.
- **Student Response:** pH = 2.802
- **Feedback:** Incorrect; please try again. Five attempts remaining.

### Part D
- **Situation:** A mixture formed by adding 53.0 mL of 2.5×10⁻² M HCl to 160 mL of 1.5×10⁻² M HCl.
- **Requested:** Express the pH of the solution to two decimal places.
- **Student Feedback:** No response provided within the image context.
