How many grams of Na3PO4 will be needed to produce 425 mL of a solution that has a concentration of Na plus ions of 0.900 M?

I must assume that this is a decomposition reaction, though you do not tell me! Balanced equation. Na3PO4 -> 3Na(+) + PO4(3-) Get moles Na ions. Molarity = moles of solute/Liters of solution (425 ml = 0.425 Liters ) 0.900 M Na(+) = mole Na(+)/0.425 Liters = 0.3825 mole Na(+) Drive against Na3PO4 0.3825 moles Na(+) (1 mole Na3PO4/3 moles Na(+))(163.94 grams/1 mole Na3PO4) = 20.9 grams sodium phosphate needed
