Limiting Reactant Practice
Dr. Slotsky Chemistry II
Given the following reaction:
PCl3 + 3 H2O  H3PO3 + 3 HCl
1) Given 3.00 moles of PCl3 and 3.00 moles H2O, which is the limiting reactant?
Which is the excess reactant?
How many moles of HCl will be produced?
How many grams of HCl is this?
2) Given 75.0 g PCl3 and 75.0 g H2O, which is the limiting reactant? Which is the
excess reactant? Hint – convert these both into moles first!
How many moles of HCl will be produced?
How many grams of HCl is this?
