Iron(II,III) Oxide Fe3O4 Molar Mass, Molecular Weight
Fe3O4 + FeO --> Fe2O3. Next, we'll use the law of conservation of mass to balance the equation. According to this law, the total mass of the reactants must equal the total mass of the products. We'll start by assuming that the number of moles of FeO in the mixture is 1.0. Then, the number of moles of Fe3O4 can be calculated as follows:
for every three Fe, it produces 1 Fe3O4, meaning the ratio is 3:1. if you have 0.358 moles of Fe, that means the number of moles of Fe3O4 will equal to one third of that, thus . moles of Fe3O4 = 1/3 x 0.358 = 0.119. Simplify. Expand. heart outlined
