Explanation / Answer

Answer

[Ag+] = 1.00×10-9M

[Zn2+] = 0.080M

Explanation

Equal volumes are mixed, so dilution factor for both solution is 2

Concentration of ZnCl2 = 0.160M/2 = 0.080M

Concentration of Zn2+ = 0.080M

Concentration of Cl- = 2×0.080M = 0.160M

Ksp of AgCl = 1.6×10-10M2

[Ag+][Cl-] = 1.6×10-10M2

substituting Cl- concentration

[Ag+] × 0.160M = 1.60×10-10M2

   [Ag+] = 1.00×10-9M
