    π = iMRT

    π is osmotic pressure

    i is van't Hoff number (1 for Hemoglobin)

    M is molarity = moles/liter

    R is gas constant (0.082)

    T is temperature in K = 273 + 15 = 288 deg

    First calculate M by calculating moles in 19.85 mg of Hb

    Then divide that by 0.0165 L

    Then plug in value for M into the above equation and solve for π
