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?

  • Chemistry -

    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
