Question

What is the charge on an individual electron, if one F is equivalent to 96,487 C/mole?
A.$5.76 \times {10^{28}}{\text{C}}{{\text{e}}^ - }$
B.$6.022 \times {10^{23}}{\text{C}}{{\text{e}}^ - }$
C.$1.6 \times {10^{19}}{\text{C}}{{\text{e}}^ - }$
D.$1.6 \times {10^{ - 19}}{\text{C}}{{\text{e}}^ - }$

Answer 1

Hint: The electric charge carried by a single proton, or, equivalently, the magnitude of the negative electric charge carried by a single electron, which has charge 1 e, is known as the elementary charge. This fundamental physical constant is the elementary charge. e is frequently referred to as the elementary positive charge to prevent confusion about its sign.

Complete answer:
Michael Faraday is commemorated with the Faraday constant, which is represented by the letter F. This constant indicates the amount of electric charge per mole of electrons in chemistry and physics. The Faraday constant is frequently used in electrolysis calculations. To calculate the chemical amount (in moles) of the element that has been oxidised, divide the amount of charge in coulombs by the Faraday constant.
Using Faraday's law of electrolysis, the value of F was initially established by measuring the quantity of silver deposited in an electrochemical process in which a measured current was transmitted for a specified duration.
The Faraday constant is the amount of electric charge per mole of electrons, represented by the sign F and named after Michael Faraday.
It is presently acknowledged to have a value of 96487C/mole.
F has a straightforward relationship with two additional physical constants.
${\mathbf{F}} = {\mathbf{e}} \cdot {{\mathbf{N}}_{\text{A}}}$
where
${\text{e }} \approx 1.6021766 \times {10^{ - 19}}{\text{C}}$
${{\text{N}}_{\text{A}}}{\text{ }} = 6.022 \times {10^{23}}\;{\text{mo}}{{\text{l}}^{ - 1}}{\text{ }}$
e is the elementary charge or the magnitude of an electron's charge, and Na is the Avogadro constant (the ratio of the number of particles, N, which is unitless, to the amount of material, n, in units of moles). This is because the amount of charge in one electron multiplied by the number of electrons in a mole equals the amount of charge in one electron multiplied by the number of electrons in a mole.
Hence option D is correct.

Note:
The "faraday," a unit of electrical charge, is related to Faraday's constant. It's not as well-known as the coulomb, although it's occasionally employed in electrochemistry. The Faraday constant F = "1 faraday of charge per mole" as expressed in faradays. This faraday unit should not be confused with the farad, which is a separate capacitance unit (1 farad = 1 coulomb / 1 volt).
