1. What is the osmotic concentration of a solution containing 300 mM NaCl and 100 mM glucose? Is it iso-, hypo-, or hyper- osmolar? A. 700 mOsm/L, hyper-osmolar B. 600 Osm/L, iso-osmolar C. 200 Osm/L, hypo-osmolar D. 400 mOsm/L, hyper-osmolar 2. Ocean water has a high salt concentration compared to body fluids. If you were adrift at sea drinking seawater will not help you, and may make you even more dehydrated! What explains this? A. Water diffuses from body tissues...

A dilute salt water solution has an osmotic pressure of 5 atm at 15 degrees C. Calculate the difference between the chemical potential of the water in the solution and that of pure water. Assume that the density of the solution is the same as that of pure water. The volume of the solution is 1 liter. The density of water is 1 g/cm3. Hint: since the solution is dilute, we can approximate by saying the volume of the solution...

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...
