Answer:
As Per Given Information
Number of moles SO₂ ( Sulphur dioxide ) is 0.30
We 've been asked to find the number of atoms in given moles of Sulphur dioxide .
Value of Avogadro Number is 6.022 × 10²³ mol⁻¹
For finding the number of atoms we will use formale

Putting the given value we obtain

So, the number of atoms in sulphur dioxide is 1.8066 × 10²³
