| 1. Let’s write down the equation of the proceeding reaction:
Fe + CuSO4 = Cu + FeSO4;
2.Calculate the chemical amount of the interacting iron:
n (Fe) = m (Fe): M (Fe) = 5.6: 56 = 0.1 mol;
3. find the amount of copper sulfate:
n (CuSO4) = m (CuSO4): M (CuSO4);
M (CuSO4) = 64 + 32 + 4 * 16 = 160 g / mol;
n (CuSO4) = 64: 160 = 0.4 mol;
4.In the absence of iron, we determine the amount of released copper:
n (Cu) = n (Fe) = 0.1 mol;
5.Calculate the mass of copper:
m (Cu) = n (Cu) * M (Cu) = 0.1 * 64 = 6.4 g.
Answer: 6.4 g.
