How many moles of iron, Fe, are produced with 156.1 grams of magnesium, Mg?

b. 4.28mol Fe

Explanation:

The chemical equation in this question is given as follows:

3Mg + Fe2O3 → 2Fe + 3MgO

According to the equation;

3 moles of Mg produces 2 moles of Fe

Molar Mass of Mg = 24.31g/mol

Mole = mass/molar mass

Mole = 156.1/24.31 = 6.42mol

If 3 moles of Mg produces 2 moles of Fe

6.42 moles of My will produce 6.42 × 2/3

= 12.84/3

= 4.28mol of Fe.
