Question

One millimole of Ni(NO₃)₂ dissolves in 230.0 mL of a solution that is 0.300 M in ammonia.
The formation constant of Ni(NH₃)₆²⁺ is 5.5×10⁸.

What is the initial concentration of Ni(NO₃)₂ in the solution?

I already have this answer which is 4.35E-3, but I cannot figure out the second part which is:

What is the equilibrium concentration of Ni²⁺(aq ) in the solution?

and the answer IS NOT 1.08E-8
