Calculate the osmotic pressure of this solution.
18..6 grams of solute with molecular mass of 8940 grams are dissolved in enough water to make 1.00 dm3 of solution at 25 celsius. What is the osmotic pressure of the solution?

DrBob222,
pi = MRT
moles = grams/molar mass.
Solve for moles. Then use moles in
M = moles/L to solve for M, then pi.
