Question

The formula of is O3. If one mole of ozone contains x atoms, how many atoms will one mole of oxygen gas contain?
please give explaination in english ~thx~

Answer 1

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

Answer 2

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.)
