MF16014: What is the pH of a solution prepared by mixing 25.00 mL of 0.10 M methylamine wiht 25.00 mL of 0.10 M methylammonium chloride? Assume that volumes are additive and that Kb = 3.70 x 10-4 for CH3NH2.

If you know how to use the Henderson-Hasselbalch equation, this is the time.
(base) = 0.025*0.1/0.050
(acid) = 0.025*0.01/0.050
