Correct option is B
Ozone (O₃) is a molecule made up of three oxygen atoms. To calculate the molecular mass of ozone, we consider the atomic mass of oxygen, which is approximately 16 g/mol.
- Since ozone has three oxygen atoms:
- Molecular mass of ozone = 16 g/mol × 3 = 48 g/mol.
Additional Information:
- Ozone (O₃) is an allotrope of oxygen, where three oxygen atoms are bonded together. It plays a crucial role in protecting the Earth from harmful ultraviolet radiation by absorbing UV light in the stratosphere.
- Atomic mass of Oxygen (O): 16 g/mol. This is the mass of a single oxygen atom.
- Molecular mass of ozone: 48 g/mol.
Other Options:
- 32 - This is the molecular mass of O₂ (diatomic oxygen), not ozone.
- 16 - This is the atomic mass of a single oxygen atom, not the molecular mass of O₃.
- 18 - This is the molecular mass of water (H₂O), not ozone.
