Solution Summary: The author explains the Faraday's first law of electrolysis, which states that the mass of the substance is directly proportional to the charge passed.
Definition Definition Law that is the combined form of Boyle's Law, Charles's Law, and Avogadro's Law. This law is obeyed by all ideal gas. Boyle's Law states that pressure is inversely proportional to volume. Charles's Law states that volume is in direct relation to temperature. Avogadro's Law shows that volume is in direct relation to the number of moles in the gas. The mathematical equation for the ideal gas law equation has been formulated by taking all the equations into account: PV=nRT Where P = pressure of the ideal gas V = volume of the ideal gas n = amount of ideal gas measured in moles R = universal gas constant and its value is 8.314 J.K-1mol-1 T = temperature

Interpretation Introduction
Interpretation:
The time of fuel cell operate before the hydrogen runs out has to be determined.
Concept introduction:
The Faraday’s first law of electrolysis state that the mass of the substance (m) deposited at any electrode is directly proportional to the charge (Q) passed. The mathematical form of the Fraday’s first law is written as’
m=(QF)(MZ)
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 valency number of ions of the substance (electrons transferred per ion).
In the simple case of constant current electrolysis, Q=I×t leading to
m=(I×tF)(MZ) (1)
The above formula is written in terms of the number of moles (n),
n=(I×tF)(1Z) (2)
Here, t is the total time the constant current (I) is applied.
