Expert Answer

Step 1

The Faraday’s first law of electrolysis state that the mass of the substance  deposited at any electrode is directly proportional to the charge  passed. The mathematical form of the Fraday’s first law is given below.

Here,

The symbol F is the Faraday’s constant.

The symbol M is the molar mass of the substance in grams per mol.

The symbol Z is the va...
