Oxygen Copper
What is the mass of oxygen in copper oxide?
- The initial mass of copper powder and glass: 83.620g - the final mass of copper oxide and the glass after the reaction: 89.920 g - the increase in mass equal to the additional mass of oxygen - The number of moles of oxygen in the copper oxide, given a molecular weight of oxygen euqal to 16.00 g / mol
The added oxygen to copper is 3.300 grams. 89.920 to 83.620 = 3.300 g of oxygen is 0.2063 moles of oxygen. 3.300 g O x (1 mol O / 16.00 g O) = 0.20625 mol O Now if we know that the mass of glass, we can determine the mass of Cu, the moles of Cu and formula empirical copper oxide.
