We have been given a task to calculate the molar mass of a solute (x polymer with mass given) from the volume of a solvent (toluene) and osmotic pressure and temperature of the solution. To me it seems impossible, because I haven't found a single way to calculate the volume of the solution (which is required to calculate consentration) with given information. Is there another way to calculate this without consentration? Am I missin something? Would exact numbers help? Plz help

Hint: you don't need the volume to find the concentration.
And you are probably expected to assume the volume of the solution is just that of the solvent. It is never exact, but for reasonably diluted solutions it is a good approximation.
