Answer:
102 g Al₂O₃
Explanation:
The theoretical yield is the mass of product calculated via the molar masses and balanced chemical equation.
The limiting reagent is the reactant that is completely reacted before the other reactant(s) are used up. Since Al produces the smaller amount of product, it appears that Al is the limiting reactant. You can only make as much product as the limiting reactant allows. As such, the theoretical yield is 102 grams Al₂O₃.
