Answer:
If both (A) and (R) are correct and (R) is the correct explanation of (A).
1 mol of O
2
→ 2 atoms.
Therefore no. of atoms in 1g O
2
=
32
1
×2×6.02×10
23
=
16
6.02×10
23
Similarly , no. of atoms in 1g O
3
=
48
1
×3×6.02×10
23
=
16
6.02×10
23
They have same no. of atoms
Mass of 1 mole is its gram- atomic mass.
