Analyze Hematite $\left(\mathrm{Fe}_{2} \mathrm{O}_{3}\right)$ and magnetite $\left(\mathrm{F}_{3} \mathrm{O}_{4}\right)$ are two ores used as sources of iron. Which ore provides the greater percent of iron per kilogram?
Added by Jose Angel R.
Step 1
Calculate the molar mass of each compound: - Hematite: 2(55.845) + 3(16.00) = 159.69 g/mol - Magnetite: 3(55.845) + 4(16.00) = 231.53 g/mol Show more…
