Answered by kitor
What is molar concentration of solution?

how many moles of solute are in solution?

What is the molar mass of solute?
Answered by DrBob222
pi = MRT
pi is osmotic pressure in atm.
M is molarity
R = 0.99206
T = 24 C converted to kelvin.

Then M = mol/L. You know L and M, solve for mols.

Then mols = grams/molar mass
You know mols and grams, solve for molar mass.
