I need help with this online chemistry problem. Help!!!?

calculate the Eo and then use this value to calculate the Ecell in volts.

A voltaic cell operates at 298 K according to the following reaction:

4 Fe2+ (aq) + O2 (g) + 4 H+(aq) → 4 Fe3+ (aq) + 2 H2O (l)

What is the emf of this cell when [Fe2+] = 6.5908E-4 M, [Fe3+] = 0.699 M, pressure O2 = 0.540 atm and pH = 3.10?
