What is the pH of a solution prepared by adding 4.000 grams of NaOH to a 50.00 mL of a buffer that is 2.00 molar both in acetic acid and sodium acetate? (Assume final volume is still 50.00 mL)

i did .1 mols of AC- + .1 mols of OH gives me .2 mols of AC.

the .2 mols of AC reacts with water
AC- + H20---> OH- + HAC

so the M is .2/.05 L = 4M

to solve for the OH conc i did X^2 / 4 = 5.6 x 10^-10. and solving for the pH i get 9.675

is this right?
