How to Calculate pH at Equivalence Point in Titration?

[OasisJuice]

A 10.00 mL solution of 0.2500 M CH3COONa is titrated with 0.1300 M HCl to the equivalence point.
CH3COO− + H+ → CH3COOH
volume of HCl required=19.23 mL

Calculate the pH of the solution at the equivalence point.

I've tried this a million ways and still keep getting it wrong. Also, my chemistry prof doesn't respond or have office hours so I'm kind of on my own :( Thank you in advance for your help :).

You need the dissociation constant for acetic acid. It is a weak acid, and therefore the equivalence point pH will be greater than 7.
