Chemistry

A 125.0 −mL sample of a solution that is 2.8×10−3 Min AgNO3 is mixed with a 220.0 −mL sample of a solution that is0.10 M in NaCN . After the solution reaches equilibrium, whatconcentration of Ag+(aq) remains?

I have tried different ways and come up with these answers, allincorrect:

[Ag+] = 5.5e-15 M

[Ag+] = 1.9e-15 M

[Ag+] = 1.3e-22 M

Please show work.
