Pt | Cu²⁺ (aq) | Cu⁺ (aq) || Fe²⁺ (aq) | Fe³⁺ (aq)| Pt

The cell is constructed by preparing one half-cell with a solution containing 8.33 * 10^-3 M FeCl₃ and 1.67*10^-2 M FeCl₂, and preparing the other half-cell with a solution containing 8.33*10^-3 M CuCl₂ and 0.025 M CuCl. Calculate the cell potential once the half-cells are connected to each other. E°(Cu²⁺/Cu⁺) = 0.16 V; E°(Fe²⁺/Fe³⁺) = 0.77 V
