A chemistry graduate student is given 450. mL of a 0.70M methylamine (CH3NH₂) solution. Methylamine is a weak base with K₁ = 4.4 × 10. What mass of CH3NH₂Cl should the student dissolve in the CH3NH₂ solution to turn it into a buffer with pH = 10.16? You may assume that the volume of the solution doesn't change when the CH3NH₂Cl is dissolved in it. Be sure your answer has a unit symbol, and round it to 2 significant digits. 0 x
