Direct reduction of cobalt : Co^(2+)aq. + 2e -> Co(solid)

The current of 1.00 uA used to deposit Cobalt over time, which corresponds to 6.00 x 10^{-4} coulomb of charge Q. Assume all the current has faradic current and the reaction shown was the only reaction that happened during the electrodeposition or deposition (with the same crystal and QCM from (1))

(a) define faradic current?

(b) the theoretical m of the crystal?

(c) the theoretical F of the crystal?
