In this exercise, using the Henderson-Hasselbach equation, you will be asked to chose a pair ideal for the preparation of a 100mL buffer solution with a pH of 9.02
The selected pair is: Ammonia (pkA: 9.25) and Ammonium Chloride (pkA: 9.24)

pH = pKa + log [base]/[acid]

volume of 0.1 M acid needed: 63 mL
volume of 0.1 M base needed: 37 mL

Can someone show me the process how these answers were obtained and if they are correct?
