Vedclass · Answer

(C) The formula to calculate the number of moles of electrons $(n)$ is given by $n = \frac{I 	imes t}{F}$,where $I$ is the current in amperes,$t$ is the time in seconds,and $F$ is Faraday's constant $(96500 \ C/mol)$.Given: $I = 2 \ A$,$t = 20 \ minutes = 20 	imes 60 \ s = 1200 \ s$.Substituting the values: $n = \frac{2 	imes 1200}{96500} = \frac{2400}{96500} \approx 0.02487 \ mol \ e^{-}$.Thus,the number of moles of electrons is $2.487 	imes 10^{-2} \ mol \ e^{-}$.
