when a 424-g of iron powder is burned in an oxygen atmosphere, 0.606-g of a reddish brown oxide is obtained. Determine the empirical formula of the oxide.

  • science - ,

    424 g of Fe is 424/55.85 = 7.59 moles

    Is that 0.606 g or 606 g of brown oxide?

    Recheck your numbers. If it is 606 g, then 182 g or 11.38 moles are oxygen atoms. That is a 1.50:1 O/Fe ratio

    The empirical formula is Fe2O3
