Recall: For electrolyte solutions, the osmotic pressure (∏) of the solution is given by:
where i = van't Hoff factor of the electrolyte, M = molarity of the solution, R = universal gas constant, T = temperature
Given that blood exert the same osmotic pressure as a 0.15 M NaCl solution, which of the following could be the contents of the second beaker?
a. 0.008 NaCl
b. 0.15 NaCl
c. 0.68 NaCl
