Question

b)
State Raoult's law. How is the molecular
mass of a solute determined from lowering
of vapour pressure measurement ?​

Answer 1

Explanation:

a law stating that the freezing and boiling points of an ideal solution are respectively depressed and elevated relative to that of the pure solvent by an amount proportional to the mole fraction of solute.

a law stating that the vapour pressure of an ideal solution is proportional to the mole fraction of solvent.
