There are three atoms of oxygen in every molecule of NaClO3. Since the atomic mass of Na is 23, that of Cl is 35.5, and that of O is 16, we can also say that oxygen is (16*3) / (23 + 35.5 + 16*3) = 0.45 = 45% of NaClO3 by mass.

Molecular mass of NaClO3 = 106.5 g/mol
Molecular mass of O = 16 g/mol
So, the amount of oxygen in NaClO3 is three atoms of oxygen (equal to 16 g/mol x 3 =48 g), that means :
(48 / 106.5 ) x 100% = 45.07%
Good luck!
