a current of 4.5a is passed through a solution of gold salt for 1 hour 45 minutes.calculate the number of moles of gold deposited according to michael faraday's law

According to Michael Faraday's law, the number of moles of gold deposited is equal to the current multiplied by the time multiplied by the Faraday constant (96,485 coulombs per mole).

Therefore, the number of moles of gold deposited is equal to 4.5 x 1.75 x 96,485 = 681,818.75 moles.
