The average osmotic pressure of blood is 7.7 atm at 25.0c. What molarity of a sterile saline (i.e., aqueous sodium chloride) solution is isotonic with blood? (Use a van't Hoff factor of 2.00 for sodium chloride.) Assuming that the density of the sterile saline is 1.0 g/mL, what is the mass percentage of this solution?
