Question

Briefly explain the two ways Avogadro's number was calculated.​

Answer 1

The value of Avogadro's number was obtained by dividing the charge of a mole of electrons by the charge of a single electron which is equal to 6.02214154 x 1023 particles per mole.

Answer 2

The most common used way is

• n=Charge of one mole of atom /charge of one single atom

There can be another derived way

• No of molecules=No of moles ×Avagadro no
• Avagadro no=No of molecules/No of moles
