Answer:
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.
