One-half of an electrochemical cell consists of a pure nickel electrode in a solution of Ni²⁺ ions; the other half is a cadmium electrode immersed in a Cd²⁺ solution.

Compute the cell potential at 25°C if the Cd²⁺ and Ni²⁺ concentrations are 0.5 and 10⁻³ M, respectively. 

Give your answer to 3 decimal places.
