Ratio of number of atoms in one mole of oxygen molecule to ozone is _____.
23
Oxygen is diatomic (O2) and ozone is triatomic (O3).
Thus,
1 mole of oxygen = 6.022 × 1023 molecules of O2 = 2 × 6.022 × 1023 atoms of O.
1 mole of ozone = 6.022 × 1023 molecules of O3 = 3 × 6.022 × 1023 atoms of O
The ratio is = 2×6.022×10233×6.022×1023 = 23
