What amount of copper is required to obtain 20 g of copper (II) oxide CuO?
| July 4, 2021 | education
The reaction equation for producing copper oxide: 2Cu + O2 = 2CuO.
1) Find the molar mass of copper oxide. To do this, we will use the periodic table: 64 + 16 = 80.
2) Find the amount of copper oxide substance. To do this, divide the mass of the oxide by its molar mass: 20/80 = 0.25 mol.
3) According to the reaction equation, there are two moles of copper for two moles of copper oxide. This means that the amount of copper substance is 0.25 mol.
Answer: the amount of copper substance is 0.25 mol.
