Calculating Changes in Buffer Solution Question

I need help with part ii) of the question.

(i) If 25.00 mL of 0.224 M ammonia were mixed with 50.00 mL of 0.138 M ammonium chloride, what would be the pH of the final solution (Ka of NH4+ = 5.8x10–10) ?
(ii) To what value would the pH change if 0.035 g of sodium hydroxide were added to this solution?
