Question

What is the magnitude of the charge of one mole of electrons?

• A. Less than 1 Coulomb
• B. Between 1 and 10 Columbus.
• C. Between 10 and 100 Columbus.
• D. Greater than 100 Columbus.

Answer 1

The correct option is D

Greater than 100 Columbus.

The charge of an electron $=1.602\times {10}^{-19}$

1mole $=6.022\times {10}^{23}$

Charge of one mole of electrons $=1.602\times {10}^{-19}\times 6.022\times {10}^{23}$

$=96472.4C$ which is clearly greater than 100 C.
