**Data**

- **Molarity of the NaOH solution, M:** 0.250 M

- **Initial buret reading, mL:**
  - 2.10 mL
  - 0.00 mL
  - 6.0 mL

- **Final buret reading, mL:**
  - 38.60 mL
  - 34.30 mL
  - 40.4 mL

- **Volume of NaOH solution, mL:**
  - 36.50 mL
  - 34.30 mL
  - 34.4 mL

- **Volume of CH₃COOH, mL:** 10.00 mL

- **Concentration of CH₃COOH, M:**
  - 0.9135
  - 0.8575
  - 0.8600

- **Mean concentration of CH₃COOH, M:** 0.8777

**Calculation**

\[
\frac{m_1V_1}{n_1} = \frac{m_2V_2}{n_2}
\]

- **Molarity (mol/L):** Number of moles (mol) = Molarity × Volume
  - 0.009125 = 0.25 × 0.0365
  - Conversion factor used: \( \frac{x 10}{1} \)

Example calculations:
- \( 0.085 = 0.25 \times 0.0344 \)
- \( 0.86 = \frac{0.0086}{0.010} \)

The calculations were done to find the molarity of the acetic acid solution in different trials, and the mean concentration was calculated as 0.8777 M.
