Jul 11, 2010 Assume a 100-g sample of each ore. Convert that amount to moles by dividing by the ore's respective molecular weight, and then take the ratio of iron in the ore, and the ore itself. Then multiply by the molecular weight of iron to find the weight of iron in that 100 g sample. The mass percent would be massFe / massSample * 100%.

Feb 11, 2012 Find the mass weight of an Iron atom (55,845). Then find the atom mass of FeCO3 (by adding the atom mass of iron to that of Carbon(12,0107) and three times that of Oxygen(3x16,00=48). Then divide the atom weight of Iron (55,845) by that total (115,8557) and multiply the answer by 100 to get a percentage. 55,845/115,8557=0.48202203258

Uses of Hematite (Iron Ore) Hematite is the world’s most important ore of iron. Although magnetite contains a higher percentage of iron and is easier to process, hematite is the leading ore because it is more abundant and present in deposits in many parts of the world. Hematite is mined in some of the largest mines in the world.

Introduction: In this experiment, oxidation/reduction (or redox) will be used in the titration analysis of an iron compound. We will use potassium permanganate, KMnO4, as the titrant in the analysis of an unknown sample containing iron to determine the percent iron by mass in the sample.

Your sample mass is part of your data so you need to find the grams of iron from your titration data. You know the molarity and volume of the KMnO4 and you can determine the gram equivalent mass of iron and the atomic mass of iron. Thus you can calculate the grams for iron present in each of your samples and then the percent iron in the unknown.
