The Empirical Formula of a Copper Oxide

Purpose:

To convert an unknown copper oxide to copper (Cu) metal using natural gas to provide a reducing environment as shown below:

Cu O (s) + CH (g) ?? Cu (s) + Co (g) + H O (g)

From the mass difference between the unknown copper oxide and the Cu metal generated at the completion of the reaction and the molar mass of Cu and oxygen, the empirical formula of the original copper oxide can be calculated...
