A sample of electrons is found to have a total charger of -5.4475X10^10 C. How many electrons are in this sample?
Faraday's Constant, F, corresponds to the total charge of 1 mole of electrons.
F = 96500 Columb Per Mole
No. Of Moles of Electron In The Sample
= Total Charge / Faraday's Constant
= 5.4475X10^10 / 96500
No. of Electrons In The Sample
= No. of Moles X Avagadro's Constant
= (5.4475X10^10 / 96500) X (6.023X10^23)
