Help with 13
Solution B has greater solute (solute "solute particles") concentration than does solution A. Solution A is hypoosmotic to Solution B. 13. You are instructed to make one liter of 150 mM of NaCI. Given the salt (NaCl) and equipment needed for weighing and measuring volumes, tell exactly how you would make this solution. (show all calculations). What is the osmolarity of this solution?

Saturated, Unsaturated & Supersaturated Solutions Solution, in which the concentration of solute is that determined by its solubility (at given temperature) is called SATURATED solution. One cannot add more solute to such a solution. We also say that a saturated solution is in equilibrium with pure solute: If we add solid Nacl to an already saturated solution of NaCl, that solid remains in equilibrium with dissolved Naci. Solution containing less solute than would be in the saturated solution, is UNSATURATED...
