This question involves two calculations. The answer to the first part will be
used for calculating the second part.
Aluminum powder, Al, will react and burn with oxygen gas, O2, to produce
aluminum oxide, Al2O3, according to the following balanced equation:
4 Al + 302
+ 2Al2O3
a) If 85.1 grams of aluminum react with excess oxygen in the air, how many
grams of aluminum oxide, Al2O3, will theoretically be produced?
b) If after the reaction is completed, 116.9 g of Al2O3 were actually
recovered and measured, what is the percent yield of the reaction?
