a student used a piece of aluminum that had a mass of 2.583 grams, and treated according to the same procedure you used in this experiment.
2 AL(s) + 2 H2SO49(aq) + 4 H2SO4(aq) + 22H2O(l) ----> 2 KAL(SO4)2 * 12H2O(S) + 3H2(g)
a. How many moles of AL did the student use in this experiment?
b. How many moles of the Alum, KAL(SO4) * 12H2O, can be produced theoretically? (Hint - Use the coefficients from the balanced chemical equation.)
c. what is the mass of Alum theoretically possible? ( hint- use the molar mass of the alum calculated in question #1)
d. if the student's crystals had a mass of 32.105 g, what is the percent yield?
