Hello everyone! Would like to ask if you know about a "universal" method to recalculate FeOtot to FeO and Fe2O3 by stoichiometry? I know about a method of Carmichael, i.e. recalculation on ulvospinel and ilmenite basis, but it seems to be only for spinels (please correct me if I'm wrong).


i.e. 1 troy ounce = 31.103481 grams but a troy ounce/ton using a conversion of 31.103481 gives you only GRAMS PER SHORT TON. To complete the metric conversion you must also convert short tons to tonnes using the conversion factor 0.9071.

How do you calculate the Fe content in FeO and Fe2O3?

In Fe 2 O 3 iron is in its highest oxidation state. FeO is black, Fe 2 O 3 is red. Fe 2 O 3 is more common. FeO is a better conductor than Fe 2 O 3 . Calculate standard enthalpy of formation of FeO? You shouldn't "calculate" a standard enthalpy of formation. The beauty of standard enthalpies of formation is that they are already calculated for you. That is why they are … delineated by the ...
