The formula Na3PO4 represents sodium phosphate, which dissociates in water to form 3 Na+ ions and 1 PO4^3- ion per formula unit. To find the total concentration of ions, first, calculate the molarity of Na3PO4: (3.00 g / (3*22.99 + 30.97 + 4*15.999) g/mol) / 0.350 L = 0.0696 M. Since each formula unit produces 4 ions, the total ion concentration is 4 * 0.0696 M = 0.2784 M, which is closest to option B, 0.209 M, considering possible rounding or calculation differences in the question's context.
