A compound contains oxygen and chlorine. Its molecular mass is 166.9g. What is the molecular formula if its empirical formula is CIO3?

The molecular formula : Cl₂O₆

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

smooth muscle is composed of involuntary muscles found within the walls of organs and structures such as the esophagus, stomach, intestines, and blood vessels. those muscles push materials like food or blood through organs. unlike skeletal muscle, smooth muscle can never be under your control.

i think   the answer is c hope i'm right
