If a buffer ia made up to be 1.0M in acetic acid and 1.0M in soudium acetate, how much acid would be required to change the pH of 100ml of the buffer by 0.1 pH units?

I know that:
CHCOONa had a pKb of 9.25
CH3COOH has a pKa of 4.76.
The question is asking about equal concentrations of acid and base.

Any assitance would be wonderful
