How many moles of NH4Cl must be added to 1.0 L of a 0.050-M solution of NH3 to give a buffer solution with a pH of 9.17? The K₂ of NH4* is 5.56*10-10. Assume a negligible change in volume as the solid is added. Enter your answer in non-scientific notation to 3 decimal places. Enter only the number, not the units.
