Expert Answer:
1. Given:
Mass of O2 = 16 gm
Mass of O3 = 32 gm
Molar mass of O2 = 32 gm
Molar mass of O3 = 48 gm
No. of moles of O2
No. of moles of O3
1 mole of any substance contains 6.022 × 1023 atoms
1/2 mole of O2 will contains =
2/3moles of O3 will conatain = 
Ratio of the number of atoms present
The ratio of number of atoms is 1:2
