Concentration of Sodium Ions is 0.6 mol/L, and phosphate ions is 0.2 mol/L

Explanation:

Molarity of Phosphate Ions = Moles of Phosphate Ions / Volume of solution (L)

M of Phosphate Ions is = 0.200 moles x 1000 / 10 mL

                                 =    2/10   = 0.2 mol /L

M of Sodium ions is = 0.6 mol /L because for three Sodium Ion in solution , Sodium Phosphate produces one Phosphate Ion.
