Raoult's Law is applicable to ______ solutions.
The decrease in vapor pressure of a solvent upon addition of a non-volatile solute is called ______.
The relative lowering of vapor pressure is equal to the mole fraction of the ______.
True or False: Raoult's Law can be applied to all types of solutions.
True or False: The addition of a volatile solute to a volatile solvent always increases the total vapor pressure of the solution.
True or False: The vapor pressure of a solution can be used to determine the molar mass of a solute.
True or False: The vapor pressure of a solution depends only on the temperature and not on the nature of the solute.
