0.100 moles of NaOH are combined with 0.125 moles acetic acid. The mixture is taken to a final volume of 100.00 ml. What is the expected pH of the solution? Use Ka for acetic acid of 1.76 x 10^-5

It makes it easier if you don't change screen names. Use the HH equation as in in the formic acid/sodium formate buffer
There is one difference. In the formic/formate buffer you have the components separated. In this one you must combine the acid and base, calculate how much acetate you have formed and how much acetic acid there is left to act as the cid.
