Question

AgBr(s) ⇄ Ag+(aq) + Br-(aq)      Ksp = 7.7 x 10-13
Ag+(aq) + 2NH3(aq) ⇄ Ag(NH3)2+(aq)      Kf = 1.5 x 107

When NH3 is added to AgBr(s), a combination of these reactions result:

AgBr(s) + 2NH3(aq) ⇄ Ag(NH3)2+(aq) + Br-(aq)

What mass of AgBr will dissolve in a 5.0 L container of 2.7 M NH3 solution?

* 8.6×100 g

* 2.8×10-2 g

* 5.2×100 g

* 9.2×10-3 g

* 4.6×10-2 g
