10D. Colligative property measurements are instrumental in understanding the nature of ionic solutions. The osmotic pressure of a 0.010 mol/L solution of NaBr was found to be 0.45 bar. (a) What concentration of solute particles is consistent with this osmotic pressure at 25°C? (b) Why does this value differ from the stated molarity? Assume that no errors were made in the measurements. (Hint: Remember that colligative properties reflect the actual concentration of particles in solution.)
