How to find the ph in a strong base weak acid titration?

[nvidia69]

Homework Statement

If .0200L of .100M nitrous acid is titrated using .200M NaOH solution, what will the pH be at equivalence?

Homework Equations

The Attempt at a Solution

I figured out that the volume of NaOH at equivalence is .01L, however I do not know what to do after that.

Thanks
