Could I get the FeO and O2 value from the equation "FeO total = FeO + 0.8998*Fe2O3" or molar stoichiometric equation Fe2O3 = 0.5O2 + 2FeO? It is a dumb question, but I think it is important to know the stoichiometric calculation of FeO and Fe2O3 separation. Thank you for read. I would be greateful if I could get advice on that.

Total iron (FeO*): The sum of FeO = 0.9(Fe2O3). Variation diagram: A Cartesian(x-y) diagram on which data such as major-element oxide or trace element concentrations are plotted. Since both parameters normally are not constant, the concentration of one parameter will vary with respect to the concentration of the other parameter.
How do you calculate the Fe content in FeO and Fe2O3 ...
-2 for oxygen. The oxidation number of iron depends on the oxide. +2 for Fe in FeO. +3 for Fe in Fe2O3. +2 and +3 for Fe in Fe3O4. (Note: Fe3O4 can be considered as a mixture of FeO and Fe2O3)

RPP(0) = –1.37 × FeO2 + 19.59 × FeO – 3.85, RPP(1) = –1.25 × FeO2 + 21.39 × FeO + 13.05, and FeO refers to the wt%FeO. This relation reproduces the measured values of Fe3+/Fe Total to within ±0.07 and, therefore, should permit determination values of Fe3+/Fe Total in amphiboles with Fe contents from 7 to 13 wt% FeO with similar ...

FeO converted to Fe2O3? - Answers
Iron oxides FeO and Fe2O3 react with acids in water and form salt and water so their behavior is just like bases, FeO + 2HCl = FeCl2 + H2O and Fe2O3+ 3H2SO4 = Fe2(SO4)3 + 3H2O.

Difference Between FeO and Fe2O3 | Compare the Difference ...
The key difference between FeO and Fe2O3 is that FeO has iron in +2 oxidations state, whereas Fe2O3 has iron in +3 oxidation state.. In brief, FeO and Fe2O3 are oxides of iron but having the iron atoms in different oxidation states. FeO is the chemical formula of iron(II) oxide while Fe2O3 is the chemical formula of iron(III) oxide.

First your mineral must have some constraining conditions, i.e. total number of oxygens or cations, etc. which you have as a formula in one of the cells. Then in the Fe2o3 cell you put the formula. (FeO*-FeO) x 1,11138. In the FeO-cell you now assign a value and check your "constraining condition cell" and adjust until it has the right value.
