Answer: The vapor pressure of a solution in which the mole fraction of the solute is 0.200 is 80.0 torr
Explanation:
As the relative lowering of vapor pressure is directly proportional to the amount of dissolved solute.
The formula for relative lowering of vapor pressure will be,
where,
= vapor pressure of pure solvent = 100.0 torr
= vapor pressure of solution = ?
i = Van'T Hoff factor = 1 for nonvolatile, nonelectrolyte solute
= mole fraction of solute = 0.200


The vapor pressure of a solution in which the mole fraction of the solute is 0.200 is 80.0 torr
To confirm the results of the same experiment to see if they are similar
Atoms make up everything,
compounds are 2 or more elements joined together chemically and
elements are groups of atoms that mix to create mixtures (2 it more atoms not chemically combined) and compounds.
