Problem- the half-equivalence point of a titration occurs

Problem- The half-equivalence point of a titration occurs half way to the end point, where half of the analyte has reacted to form its conjugate and the other half still remains unreacted. If 0.360 moles of a monoprotic weak acid (Ka = 4.5 Ã- 10-5) is titrated with NaOH

1) What is the pH of the solution at the half-equivalence point?
