Answer:
Ampere = colulomb/s
Ampere = colulomb/s coulomb/s x time ( in s) = coulomb
Ampere = colulomb/s coulomb/s x time ( in s) = coulomb coulomb / 96500 = faraday
Ampere = colulomb/s coulomb/s x time ( in s) = coulomb coulomb / 96500 = faraday 2.0A * 60 sec = 12 C
Ampere = colulomb/s coulomb/s x time ( in s) = coulomb coulomb / 96500 = faraday 2.0A * 60 sec = 12 C 12/96500 = 1.2 * 10^-4 moles
