First, we need to calculate the number of moles of the substance deposited:
1. Calculate the molar mass of the substance:
Molar mass = 200g / 1mol = 200g/mol
2. Calculate the number of moles of the substance deposited:
Number of moles = 200g / 200g/mol = 1 mol
3. Calculate the charge passed in Faraday:
1 mole of substance corresponds to 41.8.33×10^(-3) gC of charge passed
1 mol of charge = 41.8.33×10^(-3) gC
4. Calculate the charge passed in 2 minutes:
Using the formula: Charge = Current x Time
Charge = Current * 2 minutes
5. Calculate the current passed:
Current = Charge / Time
Current = (1 mol * 41.8.33×10^(-3) gC) / 2 minutes = 41.8.33×10^(-3) / 2 = 20.915×10^(-3) A
Therefore, the current passed through the electrolyte is 20.915×10^(-3) A.
