The number of atoms of oxygen are present in 2.50 moles of sulfur dioxide is 30.110 × 10²³.
Avogadro's number is define as the number of atoms present in one mole of any substance and it is equal to 6.022 × 10²³.
In the 1 mole of SO₂ 2 moles of oxygen are present. So that in 2 moles of SO₂, 2(2.5) = 5 moles of oxygen is present.
No. of atoms of oxygen in 5 moles of oxygen will be calculated as:
No. of atoms = 5 mole × 6.022 × 10²³atoms per mole = 30.110 × 10²³atoms
Hence number of atoms of oxygen is 30.110 × 10²³.
