Question

The charge on 1 electron is $1.602\times {10}^{-19}$coulombs. What will be the charge on 1 mole of electrons ?

• A. $1.602\times {10}^4$ coulombs
• B. $96488$ coulombs
• C. $1.602\times {10}^{-19}$ coulombs
• D. $96880$ coulombs

Answer 1

The correct option is B

$96488$ coulombs

1. 1 mole of electrons = $6.022\times {10}^{23}$ electrons
2. The charge on 1 electron is $1.602\times {10}^{-19}$coulombs
3. Therefore, charge on 1 mole of electrons = $6.022\times {10}^{23}$ $\times$$1.602\times {10}^{-19}$= $96472.44\cong \mathit{}\mathit{96488}$Coulombs.
