What is the pH of a solution that is 0.10 M CH3NH2 (methylamine) and 0.15 M methylammonium chloride?

• Chemistry -

i know i already have the Kb value of 4.4x10^-4 and a Ka value of 2.3x10^-11
and have to use the common ion effect but im not sure how

• Chemistry -

Use the Henderson-Hasselbalch equation (which is the easier way to use the common ion effect). This is a buffered solution.
