Hint:
Faraday is the unit of electrical charge. Coulomb is also a unit of electrical charge derived by The International System of Units, commonly known as SI.
Complete step by step answer:
As we know, Faraday is named after the scientist, Michael Faraday. It is denoted by the symbol F which is a unit for measurement of electrical charge.
And one faraday of electrical charge corresponds to the charge on one mole of electrons.
We can write the above statement as one faraday charge is the product of charge on one electron and the Avogadro’s number, because one mole of electrons is equal to Avogadro’s number.
From the above definition, we can derive the value 1 faraday in terms of coulomb-
\[1F={{e}^{-}}\times {{N}_{A}}\]
Where,${{e}^{-}}$is the abbreviation for electron and depicts the charge on one electron.
Since the charge on one electron= ${{e}^{-}}=1.602\times {{10}^{-19}}Coulomb$
And Avogadro’s number= $6.023\times {{10}^{23}}$,
Putting these values in the above equation, we will get-
$\therefore 1F={{e}^{-}}\times ({{N}_{A}})=1.602\times {{10}^{-19}}C\times 6.023\times {{10}^{23}}$$\simeq $96500C
Therefore, it is clear from the above derivation that 1Faraday is equal to 96500 coulomb.
So, the correct answer is [D].
Additional Information:
Coulomb is the commonly used, SI derived unit of electrical charge. Faraday is much less common than coulomb. However, it is used sometimes in electrochemical cells.
One related constant named as the Faraday Constant is also known which is commonly used in electrolysis calculations. The amount of charge in coulombs is divided by the Faraday constant which gives the chemical amount of the element that has been oxidized in moles.
Note:
It is important to remember here that Faraday is the unit of electrical charge and it should not be confused with Farad, which is the SI unit of electrical capacitance.
It is also important to write the units here while calculating the value of 1 Faraday.
