Explanation / Answer

P = MRTi, where:

P is the osmotic pressure of the solution
M is the molarity of solution
R is the gas constant (make sure the units here line up with the units of pressure)
T is the Kelvin temperature
i is the Van't Hoff factor (the number of particles in an ideal solution)

Osmotic pressure depends on the number of 'particles' as well as the concentration

C. C2H5OH < Ca(NO3)2 = C6H12O6 < NaCl
