I have to use the formula below but I don't know how! :(
Delta G = -nFE
Cell Designation : E (measured)
= Sn I Sn^2+ II Cu^2+ I Cu
Temp= 3 Celsius
Temp= 276.15 Kelvin
Delta G= ?????
Show work please!!!!

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.

how do i get voltage cell????
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.
