Question

a). If 3 mole of oxygen reacted, how many mole of iron (III) oxide would be formed from the reaction?

Answer 1

If there is 3.0 moles of oxygen consumed, there is 2.0 mol of iron (III) oxide (Fe2O3) formed.

Step-by-step explanation:

Step 1: Data given

Number of moles oxygen reacted = 3.0 moles

Step 2: The balanced equation

4Fe + 3O2 → 2Fe2O3

Step 3: Calculate moles of iron (III) oxide (Fe2O3)

For 4 moles Fe consumed, we need 3 moles of O2 to produce 2 moles of Fe2O3

For 3.0 moles O2 consumed , we need 2/3 * 3.0 = 2.0 moles of Fe2O3

If there is 3.0 moles of oxygen consumed, there is 2.0 mol of iron (III) oxide (Fe2O3) formed.
