To assign an oxidation number (N ox): The oxidation number of an elemental substance is zero. What would the balanced reaction look like, and would CrO72- be the Reducing Agent, and Fe2+ be the Oxidizing Agent? Step 6: If the number of electrons lost in the oxidation half-reaction is not equal to the number of electrons gained in the reduction half-reaction, multiply one or both of the half- reactions by a number that will make the number of electrons gained equal to the number of electrons lost. The actual molar mass of your unknown solid is exactly three times larger than the value you determined experimentally. (Use the lowest possible coefficients.) Balance all the oxygens by adding an H2O for each extra oxygen you need.
