Question

give the ratio of number of atoms present in equal masses of o2 (GMW=32) and o3(GMW=48)​

Answer 1

Explanation:

Assertion: 1 g O2 and 1 g O3 have equal number of atoms.Reason: Mass of 1 mole atom is equal to its gram - atomic mass.

1 mol of O2 → 2 atoms.Therefore no. of atoms in 1g O2 = 132 × 2 × 6.02 × 10^23 = 6.02 × 10^2316 Similarly , no. of atoms in 1g O3 = 148 × 3 × ...
