Excellent question. It turns out that the water was in excess -- so
it does not factor into the determination of the limiting reactant.<br>

<div dir="ltr">Good afternoon, I wanted to know how I was to know
how many grams of water we collected in the lab. When
documenting our data we were to record the mass of aluminum, and
the volumes for 1.4M of KOH and 9M of H2SO4, as well as the mass
of alum. I have my balanced equation to solve for the limiting
reactant however, i'm not sure what the mass of the water in the
sample was or how to get it in order to search for the limiting
reactant.
<div>Balanced Equation:</div>
<div> 2 Al(s) + 2KOH + 4H2SO4 + 22 H2O -> 2 KAl(SO4)2·12H2O +
3H2<br clear="all">
