I'm really frustrated over this. If someone could just explain what to do it would be very, very appreciated. Thanks everyone.
1. (a) How many moles of OHï€* is needed to dissolve 1.45 g of pure aluminum?
(b) How many milliliters of 2.00 M KOH is needed to dissolve this same mass of aluminum?
2. (a) How many grams of common alum (potassium aluminum sulfate dodecahydrate) can be synthesized from 1.45 g of aluminum?
(b) If you actually recover only 15.5 g of alum when you react 1.45 g of aluminum, what is the percent yield of alum in your experiment?
