Chlorine obtained by electrolysis of calcium chloride melt fully interacts with iron weighing

Chlorine obtained by electrolysis of calcium chloride melt fully interacts with iron weighing 112 g. How many grams of calcium was formed during electrolysis.

Chlorine reacts with iron to form iron (III) chloride;
1) Find the number of mol of Fe (M = 56 g / mol): n (Fe) = 112/56 = 2 mol;
2) Find the number of mol Ca: n (Ca) = n (Cl2) = (3/2) * n (Fe) = 3 * 2/2 = 3 mol;
3) Find the mass of calcium (M = 40 g / mol): m (Ca) = 3 * 40 = 120 g;
Answer: 120 g
