    Answer: -

    2 : 1

    Explanation: -

    To calculate the required mole ratio, the first step is writing the balanced chemical equation for the formation of Fe2O3 from Fe.

    The other element present with Fe in Fe2O3 is O oxygen.

    Fe reacts with oxygen to give Fe2O3.

    The balanced chemical equation for this reaction is

    4 Fe + 3 O 2 - -> 2 Fe2O3

    Now from the balanced chemical equation we see

    There are 4 moles of Fe.

    We also see there are 2 moles of Fe2O3.

    So their ratio is Fe : Fe2O3 = 4 : 2.

    For ratio, we need the simplest.

    Simplifying by diving by 2, we get Fe : Fe2O3 = 2 : 1

    The mole ratio between Fe and Fe2O3 is 2 : 1.
