<p>The pre-lab asks for the percent yield but I am unsure which
chemical formula to use, should I use reaction 4 (the final

You basically have to work through the stoichiometry of all the
reactions to get the stoichiometric relationship between the
aluminum and the alum.<br>

Let me make it really easy for you: each mole of aluminum produces
a mole of alum.<br>
