We’re being asked to determine the solution with the highest osmotic pressure.
The osmotic pressure (Π) of a solution is related to the molarity of the solution:
i = van’t Hoff factor
M = molarity of the solution (in M or mol/L)
R = gas constant (0.08206 atm • L/mol • K)
T = temperature
Place the following solutions in order of increasing osmotic pressure.
I. 0.15 M C2H6O2
II. 0.15 M BaCl2
III. 0.15 M NaI
