Quizplus · Accepted Answer

Dissolving 0.500 mol of Na2SO4 in water and diluting to 1.33 L results in a concentration of Na+ ions of (0.500 mol * 2) / 1.33 L = 0.752 M, because each formula unit of Na2SO4 produces two Na+ ions. The concentration of SO42- ions is (0.500 mol) / 1.33 L = 0.376 M, because each formula unit produces one SO42- ion.
