A certain weak acid ha with a ka value of 56110 raised to

A certain weak acid, HA, with a Ka value of 5.61*10 raised to negative 6 is titrated with NaOH. A solution is made by mixing 7.00 mmol of HA and 1.00 mmol of strong base. What is the ph? (I found the correct answer of 4.47). Then a more strong base is added until equivalence point is reached. What is pH of this solution at the equivalence point if total volume is 35.0 mL?
