2. n = number of electrons transferred. In this case that is 2. Sn ==> Sn^2+ + 2e and Cu^2+ + 2e ==> Cu
F is the Faraday constant of 95,485 coulombs
E is the cell voltage.
T is kelvin temperature. substitute and go. Don't foget the - sign.

4. Your post said "E measured" so I assume you have that given to you. If it isn't given, add the oxidation half cell to the reduction half cell to obtain Ecell.
