The molar concentration of sodium in the solution can be calculated using the formula:Molarity = moles of solute / volume of solution in litersFirst, we need to calculate the moles of sodium phosphate in the solution:moles of Na3PO4 = mass of Na3PO4 / molar mass of Na3PO4= 1.223 g / 163.9 g/mol= 0.00746 molNext, we need to calculate the volume of the solution in liters:volume of solution = 200.0 mL / 1000 mL/L= 0.2000 LNow we can calculate the molarity of sodium in the solution:Molarity of Na+ = (3 x moles of Na3PO4) / volume of solution= (3 x 0.00746 mol) / 0.2000 L= 0.1119 MTherefore, the correct answer is A) 0.1119 M.
