The molecular formula : Cl₂O₆

<h3>Further explanation</h3>

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.

<em>(empirical formula) n = molecular formula </em>

(ClO₃)n=166.9

(35.5+3.16)n=166.9

(83.5)n=166.9

n=2

(ClO₃)2=Cl₂O₆
