There are two flasks on the bench top, one flask contains a 0.50 M NaCl solution and the other contains a 0.50 M ethylene glycol solution. What can be concluded about the osmotic pressure between the two solutions?

a) Osmotic pressure is higher in the NaCl solution.
b) Osmotic pressure is higher in the ethylene glycol solution.
c) Osmotic pressure is the same in both solutions.
d) Osmotic pressure cannot be determined without additional information.
