Question 43

If one mole of electrons per sec are passing through a point across metallic wire, calculate the charge in coloumbs passing in one sec. __________


Correct Answer: 96500

Solution

The charge on one mole of electrons is one faraday, $$N_A e = 6.022 \times 10^{23} \times 1.6 \times 10^{-19} \approx 96500\text{ C}$$. So $$96500\text{ C}$$ passes in one second.
