4A1 + 302 → 2A1,03 5. If 3.17 g of aluminum, Al, is allowed to react with 2.55 g of Oz, how many grams of
aluminum oxide will be produced? (Hint: Must determine limiting reactant.)
(molar mass Al = 26.98, molar mass O2 = 32.00, molar mass Al2O3 = 101.96)

Iwill give extra points to who gets this right
