Question

Calculate the total number of electrons present in one mole of methane.

Answer 1

1 molecule of Methane contains, 6 Carbon $e^{-}$ and 4 Hydrogen$e^{-}$, in total $10e^{-}$

$1$ mole of Methane $=6.023\times {10}^{23}$ methane molecules

$6.023\times {10}^{23}$ methane molecules contain $=10\times 6.023\times {10}^{23}$ $(1methanemolecule=10e^{-})$

$=6.023\times {10}^{24}$ electrons
