The number of moles of gold deposited can be calculated using Faraday's Law, which states that the amount of substance produced is equal to the charge (in coulombs) divided by the Faraday constant (96,485 C/mol).
In this case, the charge is 4.5 A x 1.45 hours x 3600 seconds/hour = 16,020 C.
Therefore, the number of moles of gold deposited is 16,020 C / 96,485 C/mol = 0.166 moles.
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
