Alum is a compound used in a variety of applications including cosmetics, water purification, and as a food additive. it can be synthesized from aluminum metal, sulfuric acid, water, and potassium hydroxide, as seen in the following equation:

2al(g) + 2koh(aq) + 4h2so4(aq) + 10h2o > 2kal(so4) + 12(h2o) = 3h2

using the data below, determine the theoretical and percent yield for this alum synthesis. note that aluminum is the limiting reactant.
