Hello!
From tables, we know that the
pKa for Methylamine CH₃NH₂ is 10,61
. Now, we can apply the
Henderson-Hasselbach's equation
and clear for the ratio of CH₃NH₂ to CH₃NH₃Cl
So, the ratio of CH₃NH₂ to CH₃NH₃Cl should be
0,32
Have a nice day!

What can you conclude about the relative concentrations of ch3nh2 and ch3nh3cl in this buffer? for ch3nh2, pkb = 3.36?
