Question

Explain:- How can we say that one gram of oxygen molecule means one mole of Oxygen molecule?​

Answer 1

Answer:

For oxygen, which exists in nature as diatomic molecules, O2, the statement "a mole of oxygen" is ambiguous. ... Thus "1 mole of oxygen molecules" means 6.022 x 1023 O2 molecules, or 2 x 6.022 x 1023 O atoms; "1 mole of oxygen atoms" means 6.022 x 1023 O atoms.

Answer 2

One gram molecule of oxygen molecule means 32g of O2 molecule. This mass of O2 is equal the molar mass of oxygen molecule. We know that the molar mass is the mass of one mole of a substance and is equal to 6.022 X 1023 particles of that substance. So, one gram molecule of O would consist of 6.022 X 10.
