A current of `1.50` A was passed through an electrolytic cell containing `AgNO_3` solution with inert electrodes. The weight of silver deposited was `1.50g`. How long did the current flow ? (Molar mass of `Ag=108 g " mol "^(-1), 1F=96500C " mol" ^(-1)`).

Answer» Current (F)` =1.50A`
`W=1.50g`
`t=?`
Molar mass (M)`=108//mol`
`1F=96500C//mol`
`W=ZIT=("Equiy weight")/(96500)xxIxxT" "[Eq. weight =(108)/(I)]`
`1.50=(108)/(96500)xx1.50xxt`
`t=(96500)/(108)=893.52Sec`.
