The pH of the solution will be equal to 12.22.
So, you're titrating acetic acid, a weak acid, with sodium hydroxide, a strong base. The balanced chemical equation for this neutralization reaction is
SIDE NOTE The sodium cations will be spectator ions, so I didn't include them in the equation.
Determine how many moles of each species you have
Notice that you have more moles of sodium hydroxide than of acetic acid. This means that the acetic acid will be consumed completely, and you'll only be left with sodium hydroxide in solution.
The total volume of the solution will be
This means that the concentration of the hydroxide ions will be equal to
The pOH of the solution will be
Therefore, the pH of the solution will be
