Final answer:

The solution with the highest concentration of Na+ ions is Option a: .15 M Na3PO4.

Step-by-step explanation:

To determine the solution with the highest concentration of Na+ ions, we need to compare the concentrations of Na+ ions in each solution. The concentration of Na+ ions can be determined by multiplying the molarity of the solution by the number of Na+ ions in the formula of the compound.

Looking at the options:

  1. Option a: .15 M Na3PO4
  2. Option b: .45 M NaNO3
  3. Option c: .35 M NaCl
  4. Option d: .25 M Na2SO4

Comparing the formulas of the compounds, we can see that:

  1. Na3PO4 has 3 Na+ ions
  2. NaNO3 has 1 Na+ ion
  3. NaCl has 1 Na+ ion
  4. Na2SO4 has 2 Na+ ions

Therefore, the solution with the highest concentration of Na+ ions is Option a: .15 M Na3PO4, as it has the highest number of Na+ ions.
