The number of sulphur atoms in one mole molecule of sulphur $\left(S_8\right)$ is:

The correct option is D $8\times 6.023\times {10}^{23}$
The number of sulphur atoms in one molecule of a sulphur ($S_8$) are $8$

So total number of atoms in one mole $=8\times 6.02\times {10}^{23}$

Option $C$ is correct.
