Answer:
We need 1.33 moles of Fe
Explanation:
Step 1: Data given
Number of moles O2 = 1.00 moles
Step 2: The balanced equation
4 Fe + 3 O2 → 2 Fe2O3
For 4 moles Fe we need 3 moles O2 to produce 2 moles Fe2O3
Step 3: Calculate moles Fe
For 4 moles Fe we need 3 moles O2 to produce 2 moles Fe2O3
For 1.00 moles O2 we need 4/3 * 1.00 = 1.33 moles Fe
There will be produced 0.67 moles Fe2O3
We need 1.33 moles of Fe
