Determine the mass of metal that can be obtained from the interaction of 2 kg. technical copper oxide (2) containing 4% impurities, with carbon.
2 СuO + C → CO2 ↑ + 2Cu ↓
The required formula for the solution: n = m / M.
M (CuO) = 64 + 16 = 80 g / mol.
m (CuO) = 2 kg, we translate into grams: 2 kg * 1000 = 2000 g.
n (CuO) = m / M = 2000 g / (80 g / mol) = 25 mol.
n (CuO) = n (Cu) = 25 mol.
m (Cu) = n * M = 25 mol * 64 g / mol = 1600 g.
