Answer:

7.19 g of Fe2O3 will produce 0.092 mole of iron

Step-by-step explanation:

One mole of Fe2O3 reacts with 2 mole of Aluminum to produce one mole of Al2O3 and 2 mole of iron.

Mass of one mole of Fe2O3 = 159.69 g/mol

Thus, 159.69 g/mol of Fe2O3 produces two mole of Fe

7.19 g of Fe2O3 will produce


(2)/(156.9) * 7.19\\= 0.092moles of iron
