A chemistry graduate student is given 100. mL of a 1.40M methylamine (CH3NH2) solution. Methylamine is a weak base with K = 4.4 × 104. What mass of CH3NH3CI should the student dissolve in the CH3NH2 solution to turn it into a buffer with pH = 10.88? You may assume that the volume of the solution doesn't change when the CH3NH3CI is dissolved in it. Be sure your answer has a unit symbol, and round it to 2 significant digits. X ? old Ar
