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?
What happens to the vapor pressure, boiling point, and freezing point of a liquid when a solute is dissolved in the liquid to form a solution? Multiple Choice Vapor pressure increases, boiling point decreases, and freezing point decreases. Vapor pressure decreases, boiling point decreases, and freezing point decreases. Vapor pressure decreases, boiling point increases, and freezing point decreases. Vapor pressure increases, boiling point decreases, and freezing point increases. Vapor pressure increases, boiling point increases, and freezing point increases.
