What is the value of Fe/FeO Ratio in an iron ore stockpile consist of hematite and magnetite in equal amount?

Answer:

they blow contaminated air on your hands
I think you may be asking the question wrong, because ratios are not normally expressed like that. I'll assume that by Fe, you are referring to the total amount of iron, and that by Fe/FeO you are actually referring to FeO/Fe. The formula for hematite is Fe2O3, and the formula for magnetite is Fe3O4. Assuming that by equal amount you mean equal molar quantities (rather than equal weights), this mixture breaks down as follows: Fe2O3 + Fe3O4 Fe2O3 + Fe2O3 + FeO 2 Fe2O3 + FeO So we if we are calculating the ratio of moles of FeO to total moles of iron oxide, the ratio is 1/3. But if we're calculating the moles of Fe as FeO to moles of Fe as Fe2O3, the ratio is 1/5 because there are 2 moles of Fe in each mole of Fe2O3. That's about as much as I can give you without knowing more about what the question means. For example, we need to know 1) if you actually mean Fe/FeO, or FeO/Fe, 2) if the ratio is by weight, by moles of Fe, or by moles of iron oxide species, and 3) if equal amount is by weight or by moles.
