If you have 39.5g of Fe2O3 how many grams of co are requried to complete reaction

Explanation:

1. Balanced chemical equation

2. Convert 39.5g of Fe₂O₃ into moles

3. Moles of CO

i) Mole ratio

ii) Set a proportion

     ⇒ x = 0.24735mol Fe₂O₃ × 3mol CO / 1mol Fe₂O₃ = 0.7426 mol CO

4. Grams of CO
