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 ????=1.8, what is the osmotic pressure of blood at body temperature, 37 ∘C?
