Answer #1

The formula can be used  

I x t = C

I = current im amps = 125 A

t = time in seconds = ?

C =  coulombs of charge =  6.49×106 C

t = 6.49×106/125 = 51920 Seconds or 865.33 Minutes or 14.42 Hours

Hence it will take 14.42 hours to receive 6.49×106 C of charge

    To relate current, time, charge, and mass for electroplating calculations. Electroplating is a form of electrolysis in which a metal is deposited on the surface of another metal. To quantify electrolysis, use the following relationships. Electric current is measured in amperes (A ), which expresses the amount of charge, in coulombs (C ), that flows per second (s ): 1 A=1 C/s Another unit of charge is the faraday (F ), which is equal to a mole of electrons and...
