Chemistry - Electrochemistry Question with Solution | TestHub

The total charge passed can be calculated using the formula $Q=I\times t$.

Given:
Current, $I=3.00$ A
Time, $t=10.0$ hours $=10.0\times 60\times 60=36000$ s

Substituting the values:
$Q=3.00\times 36000=108000$ C

The charge of one mole of electrons is $1$ Faraday ($F\approx 96500$ C).

Number of moles of electrons $=\frac{Q}{F}$

Number of moles of electrons $=\frac{108000}{96500}\approx 1.119$

Rounding to appropriate significant figures, we get $1.12$ moles.

Answer: $1.12$
