Ni3(Po4) has a positive charge
Neutral
Na3PO4
Na3PO4+CuBr2=Cu3(PO4)2+NaBr PO4 has a charge of -3 and Cu (in this equation as shown by CuBr2) has a charge of +2, when they combine you switch the chareges and add them on as subscripts to each other. Na and Br have the opposite charges, -1 and +1, so you don't have to add them to the equation.
Sodium has a single positive charge (+), whilst phosphate ions have a 3- charge. To balance out the charges, three sodium ions are needed, so the formula will be Na3PO4.
Na3PO4 --> 3Na+ + PO43-
The solubility of anhydrous Na3PO4 is 120 g/L at 20 oC.

Na3PO4 • 12 H2O (s) ----> Na3PO4 (s) + 12 H2O (g)
Na3PO4 --> 3Na+ + PO43-
Molarity = moles of solute/Liters of solution 0.300 M Na3PO4 = moles Na3PO4/2.50 Liters = 0.75 moles Na3PO4
The solubility of anhydrous Na3PO4 is 120 g/L at 20 oC.
