Question
Aluminum and oxygen react to form aluminum oxide.
4 Al + 3 O2 2 Al2O3
a. What is the limiting reactant if 36.4 g Al are reacted with 36.4 g of O2?
O2
b. What is the theoretical yield of Al2O3, in grams?
68.8 g
c. If 22.2 g of Al2O3 are obtained, what is the percent yield?
32.3

Answers
I think the limiting reagent is Al.
Your 68.8g, however, is correct for theoretical yield of Al2O3 which means you must have used 36.4g Al to solve for g Al2O3.
The limiting reagent is the substance that is completely used.
%yield is correct.
