Question

What is the molecular mass of ozone?
1. 32u
2. 48u
3. 8u
4. 16u

Answer 1

Correct Answer - Option 2 : 48u

The correct answer is 48u.

• The molecular mass of ozone is 48u.

• Ozone (O3)
  •   It is an allotrope of oxygen.
  • It is used as an insecticide, in the purification of water to preserve food, to synthesis artificial silk and camphor and as a bleaching agent.
  • The chemical formula of ozone is given by O₃.
  • The molecular weight of oxygen is 16.
  • Hence, the molecular weight of ozone = 16x3 = 48 u.
