The number of electrons delivered at the cathode during electrolysis by a current of 1 ampere in 60 seconds is (charge on electron = 1.60 × 10–19 C)

7.48 × 1023
6 × 1023
6 × 1020
3.75 × 1020
Explanation:

$\dfrac{W}{E} = \dfrac{1 × 60}{96500}$

$=\dfrac{6}{9650}$ = no. of mole e

no. of e = $\dfrac{6}{9650}$ × 6.02 × 1023

= 3.75 × 1020
