To find the molar concentration of sodium ion in the solution, first calculate the moles of sodium phosphate (Na3PO4) using its molar mass. Then, since each formula unit of Na3PO4 releases 3 Na+ ions upon dissolution, multiply the moles of Na3PO4 by 3 to get the moles of Na+ ions. Finally, divide by the volume of the solution in liters to find the molarity.Moles of Na3PO4 = mass / molar mass = 1.223 g / 163.94 g/mol = 0.00746 molMoles of Na+ = 0.00746 mol Na3PO4 * 3 = 0.02238 mol Na+Volume of solution = 200.0 mL = 0.200 LMolarity of Na+ = moles of Na+ / volume of solution in L = 0.02238 mol / 0.200 L = 0.1119 M
