Question

You mix together a solution of Cu(NO3)2 with a solution of Na3PO4 into a large beaker and a solid precipitate forms. You forgot to measure the amount of the Na3PO4 you added into the mix but did write in your notebook that 0.600 moles of Cu(NO3)2 was added. The reaction produced 55.5 grams of Cu(PO4)2. Determine the concentration of the Na+, Cu2+, NO3-, and PO43- ions at the end of the reaction if the total volume of the solution was 250 mL.
