Question

plz answer


write the number of atom in 32 gram of oxygen molecule?

Answer 1

Hey mate here is your answer》》

And since one molecule of O2 contains two atoms, no. of atoms= 2× 6.023× 10²³. 32 gm of oxygen has 2 x 6.023x10^23 atoms. Since, oxygen exists in our nature as a molecule O2.

Hope this answer will help you..《《

Answer 2

No. of moles of O2 gas in 32g of O2 = 32/32 = 1

So, no. of molecules = no. of moles × 6.023 × 10^23

Therefore, no of molecules = 6.023 × 10^23 × 1 = 6.023 × 10^23

1 oxygen molecules has 2 atoms

So, no of oxygen atoms = 2 × 6.023 × 10^23 = 12.046 × 10^23
