Recall that molarity is the ratio of the moles of solute and the volume of solution (in liters). In other words:
Given balanced reaction: 2 Na3PO4(aq) + 3 CuCl2(aq) → Cu3(PO4)2(s) + 6 NaCl(aq)
We need to perform a mole-to-mole comparison between each Na3PO4 and CuCl2. The flow for this problem will be like this:
Consider the following precipitation reaction: 2 Na3PO4(aq) + 3 CuCl2(aq) → Cu3(PO4)2(s) + 6 NaCl(aq)
What volume of 0.170M Na3PO4 solution is necessary to completely react with 90.0mL of 0.114 M CuCl2?
