What Is the Empirical Formula of Chlorine Oxide?

[DarkPhoenix]

Homework Statement

An oxide of chlorine was analysed. A 0.366 g sample was found to contain 0.224 g of oxygen.

Calculate the empirical formula of this oxide.

The Attempt at a Solution

Cl = 0.366/35.5 = 0.10

O = 0.224/16 = 0.014

The mass of chlorine is not 0.366 it's 0.366-0.224=0.142
