Input: Consider Input: Question: In relation to the colligative properties of a solution it can be said that: 
 Options:  <1> They have their origin in the decrease of the chemical potential of the solvent by the fact of adding a solute. <2> The decrease in the vapor pressure of the solvent to which a non-volatile solute is added is directly proportional to the mole fraction of the solvent. <3> The addition of a solute to a solvent causes the range of temperatures in which the solution is maintained in the liquid state to be lower than that corresponding to the pure solvent. <4> The molal constant of descent of the freezing point depends on the nature of the dissolved solute. <5> Cryoscopic descent is a technique applicable to the determination of the molar mass of the solvent.


Output: 1
