Question

Why one mole of Oxygen gas and one mole of oxygen atoms have different masses?

Answer 1

Answer:

Hey mate here is your answer.//

Explanation:

1 mole of oxygen atom contains 6.0221 × 10 ^23 particles of 0. Because mass of 0 (oxygen atom) = 16 u. And mass of 02 (oxygen molecule ) = 16 × 2 = 32 u. Therefore, 1 mole of oxygen molecule has greater mass than 1 mole of oxygen atom.

Answer 2

IN SIMPLE WORDS, WE KNOW THAT :

✍️ Mass of one mole of oxygen gas = (16×2) unit or 32 unit.

✍️ Mass of one mole of oxygen atom = 16 unit.

✔️ This verifies that 1 mole of oxygen gas and 1 mole of oxygen atom have different masses !
