Chapter 10, Problem 55QAP
Aqueous solutions introduced into the stream y injection must have the same osmotic pressure as blood; that is, they must be "isotonic" with blood. At 25°C, the average osmotic pressure of blood is 7.7 atm. What is the molarity of an isotonic saline solution (NaCl in H2O)? Recall that NaCl is an electrolyte; assume complete conversion to Na+ and Cl- ions.
