2Al2O3 --> 4Al + 3O2. How many grams of Al (Aluminum) will be needed to produce 48 grams O2 (Oxygen)

a 20-cm-long, cylindrical graphite (pure carbon) rod is inserted into an oxidizing atmosphere at 1145 k and 1.013 x 105 pa pressure. the oxidizing process is limited by the diffu- sion of oxygen counterflow to the carbon monoxide that is formed on the cylindrical surface.
