Answer:
The number of molecules in 16 gm of oxygen are 0.5 (= 16/32 moles). Thus the number of molecules in 16 gm or 0.5 mole of oxygen gas are 0.5 x 6.023 x 10^(23) = 3.012 x 10^(23) molecules.

Answer:
Atomic mass of Oxygen is 16
= 16g/32g.
=0.5moles.
1 mole has 6.023* 10^23 molecues or atoms.
so 0.5 mole has 3.011* 10^23molecules
