A dilute aqueous solution of CaCl2 contains 0.159 grams of solute per liter of
solution. It is fully dissociated. What is the osmotic pressure of the solution
against a membrane at 20.0 °C?

  • chemistry -

    pi = iMRT
    i = 3 for CaCl2
    moles = grams/molar mass CaCl2, then M = moles/L
    R = 0.08206
    T = 20 in kelvin.
