✔ 最佳答案
1 mole of ozone O3 contain x atoms. Actually 1 mole O3 contain 3 mole oxygen atoms.x =(3) (6.023X10^23)
1 mole of oxygen O2 contain 2 mole oxygen atoms. = (2)(6.023X10^23)
=(2)(1/3)(3)(6.023X10^23) = (2/3)(x) atoms

When 1 mole of ozone O3 contain x atoms, 1 mole of O3 contain 3 mole oxygen atoms.
(Molar Mass of O :16 gmol-1
Molar Mass of O3 :3*16gmol-1=48gmol-1
Therefore1 mole of O3 contain 3 mole oxygen atoms.)
