A 271-mL of a sugar solution containing 1.79g of the sugar has an osmotic pressure of 30.1 mmHg at 35.1 degrees C. What is the molar maas of the sugar?

Answer 1

pi = MRT
Solve for M
Then M = mols/L of solution.
You have M and L, solve for moles.

Then moles = grams/molar mass
solve for molar mass
