10.00 mL of the unknown H2SO4 solution is titrated with the standardized NaOH solution (you calculated the concentration of the NaOH in Question 5). The initial buret reading (Vi) at the beginning of the titration was 0.28 mL. The final buret reading (Vf) at the end of the titration was 37.08 mL. How many moles of NaOH were added to reach the endpoint?

Suppose we were given a sample of acetic acid, CH3COOH (Ka = 1.8 x 10-5) of unknown concentration.
You titrate 25.00 mL of this solution with a 0.70 mol/L NaOH solution.
If your initial buret reading was 0.45 mL and your buret reading at your endpoint was 35.30 mL, what was the initial concentration of acetic acid in your 25.00 mL sample?
Express your answer in mol/L but do not include units in your answer. Include at least 4 decimal places in your answer.
