Calculate the number of electrons lost during electrolysis of 2 g Cl ions?

Options

A. `4.69xx10^(24)` electrons
B. `3.39xx10^(22)` electrons
C. `7.39xx10^(22)` electrons
D. `3.59xx10^(23)` electrons

Answer

B

Explanation

`underset(35.5 g)(CI^(-))to_(1//2)CI_2+underset(1 F(6.023xx10^(23)"electrons"))(e^(-))`
35.5 g loses= `6.023xx10^(23)` electrons
2 g will lose = `(6.023xx10^(23))/35.5xx2=3.39xx10^(22)`
