Intravenous, or IV, solutions used in medicine must exert the same osmotic pressure as blood to prevent a net flow of water into or out of the blood cells. The proper concentration for an intravenous NaCl solution is 0.90 g NaCl per 100 mL of solution
(sometimes referred to as 0.90% m/v).
If the van't Hoff factor of NaCl is i = 1.8, what is the osmotic pressure of blood at body temperature, 37 °C?
