Blood generates an osmotic pressure equivalent to the pressure generated by a saline solution that is 0.900 % m/m NaCl in water. This solution, used for intravenous fluids in hospitals, is called normal saline solution. Assume the solution density is 1.00 g/mL.
a) What is the molarity of normal saline?
b) What is the mole fraction of water in normal saline?
c) How many sodium ions are there in one milliliter of this solution?
d) How many grams of sodium chloride would it take to make 3.00 L of this solution?

Normal saline (0.9% w/v) solution has the same osmotic pressure
as human blood. The solution is made by dissolving 0.9 g of NaCl in
100 mL of water. Calculate the osmostic pressure of a 0.9% saline
solution at 37 oC (normal human body temperature.)
(Hint: remember that NaCl dissociates into ions when it
dissolves!)

An isotonic saline solution is an aqueous solution that has the
same value for osmotic pressure as human body cells. Isotonic
saline contains 9.0 g of sodium chloride (NaCl, MW= 58.44 g/mol)
per liter of solution. T= 37.0 c.
