At 298 K , an excess of solid Silver iodide is added to 1 L of a 0.425 M aqueous Ammonia solution. Silver ion forms the complex: A g + ( a q ) + 2 N H 3 ( a q ) ⇌ [ A g ( N H 3 ) 2 ] + ( a q ) g

Question

At 298 K , an excess of solid Silver iodide is added to 1 L of a 0.425 M aqueous Ammonia solution. Silver ion forms the complex:

$A g^{+} (a q) + 2 N H_{3} (a q) ⇌ [A g (N H_{3})_{2}]^{+} (a q)$

given $K_{s p} (A g I) = 4 \times 1 0^{- 16}$ , $K_{f} ([A g (N H_{3})_{2}]^{+}) = 1.6 \times 1 0^{7}$

atomic masses: Ag = 108, I = 127.

If the mass of AgI dissolved is $x$ mg, find $x$ . (Answer to the nearest integer)
