The equation provided doesn't make sense. What is Cu2)(s)?
Nonetheless, 667.0 kJ x 1 mol / 333.8 kJ = 1.998 moles

You've simply repeated what you wrote the first time. I have no idea what Cu2)(s) is supposed to be. I've never seen that chemical/element before. Also, you have O2 (oxygen gas) on the right side of the equation, but where did it come from? There is no oxygen on the left side of the equation.
