A chemistry graduate student is given 300. mL of a 1.40M ammonia (NH, solution. Ammonia is a weak base with K, = 1.8 x 10°. What mass of NH,Br should the student dissolve in the NH, solution to turn it into a buffer with pH =9.81? You may assume that the volume of the solution doesn't change when the NH, Br is dissolved in it. Be sure your answer has a unit symbol, and round it to 2 significant digits.
