How many moles (miles? LOL) Fe2O3 do you have in 39.62 g Fe2O3? That's
mols = g/molar mass = 39.62/159.7 = approx 0.25 which is an estimate.
The equation tells you that you will get twice as many mols of Fe (from the coefficients) so you should get approx 0.5 mols Fe.
How many miles of Fe are made with 39.62 g of Fe2O3?
2AI (s) + Fe2O3(aq) -> AI2O3 (s) + 2Fe (s)
