Total ions in 5 formula unit in  Na2ClO3 is equal to to the number of 23 nucleons in sodium atom

Explanation:

Atomic mass of Na = 23 u C = 12 u O = 16 u Cl=35.5u

The formula unit mass of any substance is equal to the sum of the atomic masses of all the atoms present in the formula unit of an ionic compound.

Therefore formula unit mass ofNa2ClO3

= 2Na + 1C +1Cl+ 3O = 2 × 23 + 1 × 12 +1×35.5+ 3 × 16

= 46 + 12 +35.5+ 48 = 141.5 u.

Total ions in formula unit in  Na2ClO3 is 5 units

Total ions in 5 formula unit in      Na2ClO3 is equal to to the number of 23 nucleons in sodium atom,It is the number of sodium atom which can adjust the formula in balanced form.
