Question

In standard IUPAC units, the Faraday is equal to 96,480 coulombs. A coulomb is the amount of electric charge passed when a current of one ampere flows for one second. What is the relationship between the Faraday constant and Avogadro's number?

A) Faraday constant is equal to Avogadro's number
B) Faraday constant is half of Avogadro's number
C) Faraday constant is Avogadro's number divided by 2
D) Faraday constant is Avogadro's number multiplied by the elementary charge
E) Faraday constant is Avogadro's number divided by the elementary charge

Answer 1

The Faraday constant is equal to Avogadro's number multiplied by the elementary charge, representing the total charge of one mole of electrons.

Step-by-step explanation:

The relationship between the Faraday constant and Avogadro's number is that the Faraday constant is equal to Avogadro's number multiplied by the elementary charge. This is because the Faraday constant (F) represents the charge in coulombs for one mole of electrons, while Avogadro's number indicates how many entities (atoms, molecules, ions, etc.) are present in one mole. By multiplying Avogadro's number by the elementary charge, you obtain the total charge for one mole of elementary charges, which is equivalent to the Faraday constant.

As it was discovered in the experiments of Michael Faraday with electroplating, about 100,000 C per mole were needed to plate singly ionized ions. Knowing Avogadro's number, the charge per ion was calculated, which led to the close estimation of the Faraday constant.
