Answer: 1:3

Explanation:

1) To state the mole ratio of a product and a reactant we need the chemical equation that shows the reaction.

2) In the case of Fe3O4 and Fe, the chemical equation is:

<span>              Fe+H2O → Fe3O4+H2.

3) Now, you balance the equation, which will give you the coefficients of each reactant and product of the chemical reaction:
</span>
<span>              3Fe+4H2O → Fe3O4+4H2

4) From that the mole ratios are:

              3 mol Fe : 4 mol 4H2O : 1 mol Fe3O4 : 4 mol H2.

5) The question requires you to find the mole ratio for Fe3O4 to Fe. Tha is:

            1 mole Fe3O4 : 3 mole Fe

So, the answer is 1:3
