Vedclass · Answer

(A) Step $1$: Calculate the total charge $(Q)$ passed using the formula $Q = I 	imes t$.Given: $I = 2 	ext{ A}$, $t = 10 	ext{ minutes} = 10 	imes 60 	ext{ s} = 600 	ext{ s}$.$Q = 2 	ext{ A} 	imes 600 	ext{ s} = 1200 	ext{ C}$.Step $2$: Calculate the number of moles of electrons $(n)$ using the relation $n = \frac{Q}{F}$, where $F$ is Faraday's constant $(96500 	ext{ C/mol})$.$n = \frac{1200 	ext{ C}}{96500 	ext{ C/mol}} \approx 0.012435 	ext{ mol}$.Step $3$: Express in scientific notation: $n \approx 1.243 	imes 10^{-2} 	ext{ mol}$.
