A steady current of 2ampere is passed in the electrolyte for 1hr 60mins.calculate the number of faraday's used ? ?

To calculate the number of faraday's used, we first need to convert the current from amperes to coulombs per second (C/s).

1 ampere is equal to 1 coulomb per second, so 2 amperes is equal to 2 coulombs per second.

Next, we need to calculate the total charge passed in the electrolyte. Since the current is 2 amperes for 1 hour and 60 minutes, the total time is 1 hour and 60 minutes = 120 minutes.

1 hour = 3600 seconds
60 minutes = 60 seconds

Total time = 120 minutes = 120 x 60 = 7200 seconds

Total charge passed = current x time
Total charge passed = 2 C/s x 7200 s = 14400 coulombs

Finally, we need to convert the total charge passed in coulombs to faraday's. 1 faraday is equal to 96485 coulombs.

Number of faraday's used = Total charge passed / 96485
Number of faraday's used = 14400 / 96485 ≈ 0.149 faraday's

Therefore, the number of faraday's used is approximately 0.149 faraday's.
