How many electrons flow through a metallic wire if a current of 0.5A is passed for 2 hrs? `(1F ="96500 C.mol"^(-1))`

Text Solution

Verified by Experts

`Q=Ixxt=0.5xx2xx60xx60=3600C`
Number of electrons flowing through the wire on passing a charge of `96500C=6.022xx10^(23)`
`therefore" Number of electrons flowing through the wire on passing a charge of"`
`3600C=(6.022xx10^(23)xx3600)/(96500)=2.246xx10^(22)`
