empirical formula of copper oxide in late nite labs

The copper changed to copper oxide upon heating. How many grams of oxygen were used in the reaction? Choose the closest answer.

a.3.664g, b. 2.518g , c. 1.042g d. 7.992g

Equation for the reaction is; 2Cu + O2 --&gt; 2CuO moles of Cu = mass/molar mass = 10/63.546 = 0.157 moles Mass of... View the full answer

The equation of reaction is as; O2 + 2Cu -------------&gt;2CuO Let us assume that the mass of Cu used to y Moles... View the full answer

• according to the experiment we had an empty crucible with Mass of 88.000 and added 10g Copper making mass of 98.000. using this information on your formula I don't get anyof the 4 available answers
