Answer:

I think you mean copper(I) oxide, Cu₂O, and that you are asking for the percentage by mass of copper in this compound. Well, look up the atomic weights of copper and oxygen; add them appropriately; divide the total for the copper by the total for the molecule; then multiply by 100 to get it as a percentage.
