What is the numerical value of one Faraday in Coulombs ?
Answer & explanation
Correct answer: option 2
The correct answer is Option (2) → 96487
One faraday (F) is the charge carried by one mole of electrons: Avogadro’s number times the charge on one electron.
\( \displaystyle F=N_A\times e=6.02\times10^{23}\ \mathrm{mol^{-1}}\times1.6021\times10^{-19}\ \mathrm{C}=96487\ \mathrm{C\,mol^{-1}} \)
So one faraday is 96487 C; for approximate calculations 96500 C is used.
