CALCULATIONS: LABEL EACH NUMERICAL VALUE IN YOUR CALCULATION WITH AN APPROPRIATE UNIT OF MEASUREMENT AND SHOW WORK. 1. Prove that aluminum is the limiting reagent in the synthesis of alum (see Eqn 2.1). a. Calculate the moles of aluminum used in the reaction and the moles of alum that could be produced from this amount. b. Calculate the moles of potassium hydroxide used in the synthesis of alum and the moles of alum that could be produced from this amount. molKOH mol alum c. Calculate the moles of sulfuric acid used in the synthesis of alum and the moles of alum that could be produced from this amount. molH2SO4 mol alum 2. Calculate the theoretical yield of alum in grams, based on the limiting reagent. theoretical yield (g alum) 3.
