For the reaction shown, calculate how many grams of each product form when the following amounts of reactant completely react to form products. Assume that there is more than enough of the other reactant.

2Al(s)+Fe₂O₃(s)→Al₂O₃(s)+2Fe(l)

1. Calculate the mass of Al₂O₃ formed when 4.8 gAl completely react. Express your answer using two significant figures.
2. Calculate the mass of Fe formed when 4.8 gAl completely react. Express your answer using two significant figures.
3. Calculate the mass of Al₂O₃ formed when 4.8 g Fe₂O₃ completely react. Express your answer using two significant figures.
4. Calculate the mass of Fe formed when 4.8 g Fe₂O₃ completely react. Express your answer using two significant figures.
