To find the volume of 0.181 M Na3PO4 solution required to react with 91.0 mL of 0.107 M CuCl2, you need to use the stoichiometry of the reaction between Na3PO4 and CuCl2.
The balanced chemical equation for the reaction is:
[ 2 \text{ Na}_3\text{PO}_4(aq) + 3 \text{ CuCl}_2(aq) \rightarrow \text{ Cu}_3(\text{PO}_4)_2(s) + 6 \text{ NaCl}(aq) ]
Use the stoichiometry of the reaction to find the moles of CuCl2 and then determine the volume of Na3PO4 solution needed based on its concentration.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
