The number of electrons delivered at the cathode during electrolysis by a current of 1 amperes in 60 second is ( charge on electron `=1.60xx10^(-19)`C)

A

`3.74xx10^(20)`

B

`6.0 xx 10^(23)`

C

`7.48 xx 10^(21)`

D

`6.0 xx 10^(20)`

Text Solution

Verified by Experts

The correct Answer is:
A
Charge=current `xx` time
charge , `Q=1A xx 60 ` sec
=60 coulumb
Now,
96500 C charge is carried by `6.023 xx 10^(23)` electron
`implies 60 ` C charge `=(6.023xx10^(23))/(96500)xx60 ` electrons
`=3.74xx10^(20)` electrons
