2Na+ + 2Cl- --> 2Na(s) + Cl2
Two electrons are transferred.
All we need to do is use stoichiometry to solve for the amount of charge transferred
1000 g Na ( 1 mol / 23 g) X (2 mols e- / 1 mol Na) X ( 96500 C / 1 mol e-) = 8.39 x 10^6 C
Current is C/s and so we must divide our charge by the time which is one hour, or 3600 seconds:
8.39x10^6 C / 3600 s = 2331 amps.
I hope this helps! Good luck :)
