The number of oxygen atoms in 1 mol of O₂ gas is 2 x (6.02 x 10²³). Hence, Option (C) is correct.
What is Mole concept ?
A mole is defined as the amount of a substance that contains exactly the Avogadro number of 'elementary entities' of the given substance.
there are 2 × Nₐ oxygen atoms,
where,
Nₐ = Avogadro's number = 6.022 × 10 ²³
= 2 × Nₐ oxygen atoms,
= 2 x (6.02 x 10²³)
Therefore, The number of oxygen atoms in 1 mol of O₂ gas is 2 x (6.02 x 10²³). Hence, Option (C) is correct.
