 The colligative molality of an unknown aqueous solution is 1.59 m. (For pure water at 20°C: Po = 17.5 torr, kf = 1.86°C/m, kb = 0.512°C/m; boiling point = 100.0000 °C, melting point = 0.0000 °C)Please see https://youtu.be/N82oBBMOv5E for assistance.

(a) What is the vapor pressure of the solution at 20°C? (Assume the solute is non-volatile and the solution is ideal.)  torr(b) What is the boiling point of the solution?  °C(c) What is the freezing point of the solution?  °C
