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).
1. if the van't hoff factor of nacl is i = 1.8, what is the osmotic pressure of blood at body temperature, 37°c?
