A chemistry graduate student is given 450. mL of a 0.50M methylamine (CH, NH,) solution. Methylamine is a weak base with K=4.4 x 10. What mass of
CH,NH, Br should the student dissolve in the CH,NH, solution to turn it into a buffer with pH = 10.96?
%3D
You may assume that the volume of the solution doesn't change when the CH,NH, Br is dissolved in it. Be sure your answer has a unit symbol, and round it to
2 significant digits.
