explain please

A chemistry graduate student is given 100. mL of a 1.30M dimethylamine ((CH3), NH) solution. Dimethylamine is a weak base with K,=5.4 x 10 ". What 2 mass of (CH,) NH,Br should the student dissolve in the (CH,), NH solution to turn it into a buffer with pH = 10.46? 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 2 to 2 significant digits. x10 ?
