Do you have a question?
What is molar concentration of solution?
how many moles of solute are in solution?
What is the molar mass of solute?
how many moles of solute are in solution?
What is the molar mass of solute?
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.
