Oxygen is an element and also elements have actually atoms. Oxygen gas is a link consisting of molecule of oxygen, through each molecule consists of 2 oxygen atom (chemically stood for as `O_2` ). The molecular load of oxygen gas is 32 (= 2 x 16) gm/mole.
Now, each mole that a substance...

Oxygen is one element and elements have atoms. Oxygen gas is a compound consisting of molecule of oxygen, v each molecule consist of of two oxygen atoms (chemically represented as `O_2` ). The molecular weight of oxygen gas is 32 (= 2 x 16) gm/mole.
Now, every mole of a substance has an Avogadro"s number (or, `6.023 xx 10^(23)` ) of particles. In other words, 1 mole the oxygen would certainly contain `6.023 xx 10^(23)` molecules. Here, us are provided with 16 g of oxygen. The number of molecules in 16 gm of oxygen space 0.5 (= 16/32 moles).
Thus the number of molecules in 16 gm or 0.5 mole the oxygen gas are 0.5 x 6.023 x 10^(23) = 3.012 x 10^(23) molecules.
Similarly, 16 gm of elemental oxygen (represented as O) would contain 1 mole that atoms, because the atomic mass that oxygen is 16 and also hence will have 6.023 x 10^23 atoms.
