**Problem Statement:**

Determine the pH at 110.00 mL of titrant during the titration of 50.00 mL of 0.400 M B (a generic base with \( K_b = 7.58 \times 10^{-9} \)) using 0.200 M HNO₃.

**Instructions:**

- Enter your answer in scientific notation with 3 significant figures.
- Do not include any units in your answer.
- Do not round any intermediate calculations.

**Note:** Your answer is assumed to be reduced to the highest power possible.

**Answer:**

Your Answer: \(\_\_\_\_\) x 10 \(\_\_\_\_\)

**Explanation:**

In this problem, you will calculate the pH of a solution at a specific point in a titration process, involving a generic base and nitric acid. To solve this, you'll need to follow these steps:

1. **Calculate the moles of the base and acid.**
2. **Use the stoichiometry of the reaction to find the concentration of the conjugate acid/base formed.**
3. **Apply the Henderson-Hasselbalch equation or pH calculation method appropriate for the system.**
4. **Express the final pH in the required scientific notation.** 

Ensure all intermediate steps are calculated without rounding, and provide the final answer with correct significant figures and notation.

Expert Solution
Step 1

Given, 

Volume of HNO3 = 110.0 mL 

Molarity of HNO3 = 0.200 M 

Volume of weak base, B = 50.00 mL 

Molarity of weak base, B = 0.400 M 

pH of the solution = ?
