What is Ecell(in volts) for a concentration cell at 25.0Cbased off the redox reactions of X(s)/ X+(aq)with the following conditions?

What is Ecell (in volts) for a concentration cell at 25.0°C based off the redox reactions of X(s) / X+ (aq) with the following conditions? Express your answer to 3 decimal places.
At both the anode and cathode the metal X is dipped in solutions containing X+.
[X+] (at the cathode) = 1.662 mol L-1
[X+] (at the anode) = 0.004 mol L-1
Which of the following metals will NOT dissolve in a solution containing 1 mol L-1 H+ ?
