The molecular formula : Cl₂O₆
Further explanation
Given
Molecular mass = 166.9 g
The empirical formula = ClO₃
Required
The molecular formula
Solution
The empirical formula is the smallest comparison of atoms of compound forming elements.
A molecular formula is a formula that shows the number of atomic elements that make up a compound.
(empirical formula) n = molecular formula
(ClO₃)n=166.9
(35.5+3.16)n=166.9
(83.5)n=166.9
n=2
(ClO₃)2=Cl₂O₆
