Pi = MRT
You know Pi (osmotic pressure) which you want to convert to atmospheres. Use 0.08205 for R and convert T to Kelvin. Calculate M, molarity.
Then M = moles/L which allows you to calculate # moles.
Finally, # moles = g/molar mass which allows you to calculate molar mass. Post your work, preferably with the problem, on a new post, if you run into trouble.
