The balanced equation for this process is
2CuO+C→2Cu+CO2 2\text{CuO} + \text{C} \rightarrow 2\text{Cu} + \text{CO}_2 2CuO+C→2Cu+CO2Calculate the atom economy of this process to produce copper.
atom economy (%)=total formula mass of desired producttotal formula mass of all reactants or products×100 \text{atom economy (\%)} = \frac{\text{total formula mass of desired product}}{\text{total formula mass of all reactants or products}} \times 100 atom economy (%)=total formula mass of all reactants or productstotal formula mass of desired product×100Give your answer to 2 significant figures.
(relative atomic masses: C = 12, O = 16, Cu = 64)
