Calculate the Avogadro's number using the charge on the electron `1.60 xx 10^(-19)C` and the fact that `96500 C` deposits `107.9 g` silver from its solution.

Explanation

`:' 96500` coulomb deposits `107.9g Ag` or `E g Ag` or `A g Ag`, where `E`, and `A` are equivalent weight and atomic weight of `Ag` respectively. `E = A` because `Ag` is monovalent. Thus `96500` coulomb charge means charge on `N` electrons where `N` Av. no.
Thus, `N xx e = 96500`
`N = (96500)/(1.60 xx 10^(-19))`
`= 6.03 xx 10^(23)` electrons
