# osmotic pressure chemistry.

posted by .

I have a question about osmotic pressure. I took a test in chemistry and this was a multiple choice question.

It said given the molar mass of each solution, which one had the high osmotic pressure.

So a high osmotic pressure, means a high molar mass or a low molar mass?

Thanks, Ms.Sue.
Changing browsers seems to cause confusion.
