calculate the osmotic pressure of a solution obtained by mixing 100ml of 0.25M solution of urea and 100ml of 0.1m solution of cane sugar at 293k

  • chemistry -

    pi = MRT
    I suppose you are to assume that 0.1m = 0.1M.
    Then 100 mL x 0.25 = millimols urea.
    100 mL x 0.1M = millimols sugar.
    Total M = total millimols/total mL.
    Solve for pi.
