• (e) none of these.

Solutions

Expert Solution

The relation between a faraday of charge of one atom of a univalent substance $$(F),$$ atom per

mole $$\left(N_{\mathrm{A}}\right)$$ and the particle charge $$(e)$$ is $$F=N_{\mathrm{A}} e$$

Rearrange the above equation for the charge of electron

$$e=\frac{F}{N_{\mathrm{A}}}$$

So, the correct answer is option (b).
