# Problem: 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

###### FREE Expert Solution

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:

$\overline{){\mathbf{\Pi }}{\mathbf{=}}{\mathbf{iMRT}}}$

where:

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
