Chemical Conversion (Stoichiometry): Aluminum Scrap to Alum Data
mass of aluminum - 0.54g
mass of water + filter paper - 42.84g
mass of alum product + watch class + filter paper - 43.70g
Calculate the mass of your alum produce - this is the actual yield of you synthesis???
Calculate the molar mass of alum [KAl(SO4)2 * 12H2O] - round the result to the nearest 0.1 gram/mol???
Calculate the theoretical yield in grams for this reaction. Assume the aluminum is the limiting reactant and use the molar mass of Al, the reaction stoichiometry, and the molar mass of alum in your calculation???
Use the actual yield (#1) and the theoretical yield (#3) to calculate the % yield for your synthesis???
They don't give me a reactant

Synthesis of Alum (Potassium Aluminum Sulfate) from Aluminum Aluminum cans can be recycled to make potassium aluminum sulfate dodecahydrate, KAK(SO)12H20, which is abbreviated to "alum". The 12 waters are part of the overall formula. Alum can be used to make dyes, printing fabrics, making paper, adhesives, pickling of food and vets use it to induce a dog to throw up. x 1 rxn 2 run 3 The following are the four reactions that lead to alum: Al(s) + 2 KOH...
