The vapor pressure of distillated water at 48 0C is 0,121 atm. A solution containing lactose has a vapor pressure of 0.119 atm at 48 0C. What is the boiling point of this solution? If it has a density of 1.24 g/mL, what is the osmotic pressure of this solution at 48 0C? Reference data: Mr (lactose)=342 g/mole ; Kb (water) =0.520 0C m-1; R = 0.0821 L atm K-1mole-1.
