Question

Approximate charge present on one mole of electrons is (charge on one electron = 1.6 × 10-19 coulomb​

Answer 1

Given:

Charge of an electron is 1.6 × 10^(-19) C.

To find:

Charge of 1 mole of electrons?

Calculation:

1 mole of electrons means 6.023 × 10²³ electrons.

So, total charge is :

$= 1.6 \times {10}^{ - 19} \times (6.023 \times {10}^{23} )$

$= 9.6368 \times {10}^{23 - 19}$

$= 9.6368 \times {10}^{4}$

$\boxed{= 96368 \: coulomb}$

$\approx 1 \: Faraday$

So, charge in 1 mole of electrons is 96368 Coulomb or 1 Faraday.

• Always remember that 1 mole of electrons is equivalent to 1 Faraday of charge.
