Calculating the composition of a buffer of a given pH Ja A chemistry graduate student is given 450. mL of a 1.10 M trimethylamine ((CH3 ) N) solution. Trimethylamine is a weak base with K, = 7.4 x 10 . What mass of (CH3 ) , NHCI should the student dissolve in the (CH3 ) N solution to turn it into a buffer with PH = 10.69? You may assume that the volume of the solution doesn't change when the ( CH, ) NHCl is dissolved in it. Be sure your answer has a unit symbol, and round it to 2 significant digits. 0 X ?
