SUMMARY

The empirical formula of chlorine oxide was determined through a mass analysis of a 0.366 g sample containing 0.224 g of oxygen. The mass of chlorine was calculated as 0.142 g, leading to a molar ratio of chlorine to oxygen. The calculations yielded a ratio of 0.10 moles of chlorine to 0.014 moles of oxygen, resulting in the empirical formula Cl7O1 after simplification.

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
