Calculate the electrode potential of a copper half-call containing 0.05M Cu(NO3).

E^0 Cu2+/Cu = 0.337 V

E = Eo - (0.0592/n)log[(Cu)/(Cu^+2)]
Substitute 2 for n and 0.05 M for Cu^+2 and 0.337 for Eo. Solve.

Am I solving for Cu or do I plug a value in for that also?

    As I stated in my response, substitute 2 for n and 0.05 M for Cu^+2. You substitute 1 for Cu metal (that is its standard state) and solve for E. E is the only unknown you have.
