Question

One mole of oxygen gas at STP is equal to _______.
(i) 6.022 × 10^23 molecules of oxygen
(ii) 6.022 × 10^23 atoms of oxygen
(iii) 16 g of oxygen
(iv) 32 g of oxygen

Answer 1

Mole represents a definite Number of particles , atoms or molecules. This Number of 6.022x 10^23 , which represents a mole is called Avogadro number ( L).
Therefore, 1 Mole of oxygen molecule at STP is 6.022x 10^23 oxygen molecules.
Hence option (i) is correct

Answer 2

Answer:

Explanation:
