A chemistry graduate student is given 450. mL of a 0.10M ammonia (NH3) solution. Ammonia is a weak base with K, = 1.8 × 10. What mass
of NH4Cl should the student dissolve in the NH3 solution to turn it into a buffer with pH = 9.11?
You may assume that the volume of the solution doesn't change when the NH4Cl is dissolved in it. Be sure your answer has a unit symbol, and
round it to 2 significant digits.
