at a temperature of 5 celsius, 21.5 mg of a non electrolyte is dissolved in enough water to make a 150.0 ml solution. the osmotic pressure of the solution is 0.200 atm. what is the molar mass of the substance dissolved

  • chemistry -

    pi = MRT
    Substitute and solve for M.

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

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