Question

How many electrons in one mole of carbon dioxide?

Answer 1

Step 1: Calculation of total electrons present in 1 molecule of Carbon dioxide

Carbon dioxide (${\mathrm{CO}}_2$), $\mathrm{C}$ has atomic numbers $6$ so it has $6$ electrons and oxygen has atomic number $8$ means it has $8$ electrons.

Total electrons present= $16+6=22$ electrons.

Step 2: Calculation of the number of electrons in one mole of carbon dioxide

In one mole of atoms or electrons, there are $6.022\times {10}^{23}$ number of atoms (Avogadro's number).

As in 1 molecule of carbon dioxide (${\mathrm{CO}}_2$), there are total 22 electrons present,

so In one mole of ${\mathrm{CO}}_2$ there will be= $22\times 6.022\times {10}^{23}$

=$132.44\times {10}^{23}$electrons.

Therefore, The number of electrons in one le of ${\mathrm{CO}}_2$ is $132.44\times {10}^{23}$ electrons.
