Answer:

3 mol of Al

Explanation:

In order to produce Fe, from Al, we have to make this reaction:

2Al + Fe₂O₃  →  Al₂O₃  +  2Fe

Ratio is 2:2

So, to produce 3 mol of Fe, I need the same amount of Al.

Answer:

There have to react 3 moles of aluminium (Al)

Explanation:

Step 1: Data given

Number of moles of Iron (Fe) = 3.0 moles

Step 2: The balanced equation

Fe₂O₃ + 2Al  → 2Fe + Al₂O₃

Step 3: Calculate moles of Aluminium (Al) needed

For 1 mol Fe2O3 consumed, we need 2 moles of Al to produce 2 moles of Fe and 1 mol of Al2O3

When there are 3 moles of Fe produced, we need 3 moles of Al to be consumed.

There have to react 3 moles of aluminium (Al)
