Question

Answer the following in one or two sentences.

How many electrons would have a total charge of 1 coulomb?

Answer 1

Charge on l e^- is 1.602 × 10^-19 coulomb.

l e^- ≡ 1.602 × 10^-19 C

∴ Number of electrons having total charge of 1 coulomb

`= 1/(1.602 xx 10^-19) = 6.242 xx 10^18`

The number of electrons having a total charge of 1 coulomb is 6.242 × 10¹⁸
