Given
m (Fe) = 14 g
m (Cu) -?
Decision
1.Write the reaction equation:
Fe + CuCl2 = Cu + FeCl2
2. Let’s find the amount of a substance by the formula n = m / M, where n is the amount of a substance, m is the mass of a substance, M is the molar mass of a substance.
n (Fe) = 14/56 = 0.25 mol
3. find the mass of copper by the formula m = n * M
m (Cu) = 0.25 * 64 = 16 g
Answer: copper mass = 16 g.
