It is primarily used in various applications, including the production of iron and steel, as a pigment in paints and coatings, and in the manufacture of ceramics. In biological contexts, iron oxides play a role in the metabolism of iron, which is crucial for numerous biological processes. Furthermore, Fe\u2082O\u2083 is a key component in the development of magnetic materials and serves as a catalyst in various chemical reactions.<\/p>\n\n\n\n<p>In summary, iron(III) oxide (Fe\u2082O\u2083) has a molar mass of about <strong>159.70 g\/mol<\/strong> and plays significant roles in industrial applications and biological systems.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>What is the name and molar mass of Fe2O3?
