A mining оperаtiоn rоаsts FeS₂ (pyrite) in oxygen, primаrily to convert the sulfur in the mineral into sulfur dioxide gas (SO₂) and the iron into iron (III) oxide (Fe₂O₃). This process is an important step in metallurgy and sulfuric acid production. The roasting reaction is: 4FeS2+11O2→2Fe2O3+8SO2 Assuming complete reaction, determine the mass of O₂ needed to completely use up 236.4 g of pyrite.
