The correct statement among the following is:
(A) 0.5 g-atom of oxygen contains Na/4 oxygen molecules.
- One gram atoms mean the exact no of atoms that are present in one mole of a given substance.
⇒ 0.5 g atom oxygen atoms mean 0.5 Na oxygen atoms.
- The no of oxygen molecules (O2) formed by 2 oxygen atoms = 1
⇒ The no of oxygen molecules (O2) formed by 0.5 Na oxygen atoms = 1/2 × 0.5 × Na = Na/4
