(0.0034 / 0.035) times 100 Percent ionization = 9.7% A solid mixture contains both MgCl2 and NaCl. When 0.5000 g of this mixture is dissolved in enough water to form 1.000 L of solution, the osmotic pressure at 25.0 Degree C is observed to be 0.3990 atm. What is the mass percent of MgCl2 in the solid? (Assume ideal behavior for the solution and that both ionic compounds dissociate completely in the water.)
