need help answering question 4, it requires you to use question 3 that is boxed in pink. thank you.

3. A student following the procedure in this experiment prepared three solutions by adding 11.50,23.00, and 34.50 mL of a 7.60x 10 M NaOH solution to 50.00 mL of a 0.112M solution of a weak acid. The solutions were labeled 1, 2, and 3, respectively. Each of the solutions was diluted to a total volume of 100.0 mL with distilled water. The pH readings of these solutions were: (1) 6.42, (2) 6.81, and (3) 7.09 (1) Convert the pH of each solution to an equivalent HO ion concentration 0 2) 10 (2) For each solution, calculate the number of moles of acid added.
