Question

When exposed to air, aluminum metal, Al, reacts with oxygen, O2, to produce a protective coating of aluminum oxide, Al2O3, which prevents the aluminum from rusting underneath. The balanced reaction is shown here: 4Al+3O2→2Al2O3 In Part A, we saw that the theoretical yield of aluminum oxide is 1.90 mol . Calculate the percent yield if the actual yield of aluminum oxide is 1.18 mol .
