Verified Answer
The relative lowering of the vapour pressure is equal to ratio between...

Here, PoA - PA, (difference in vapour pressure of pure solvent and solution): lowering in vapour pressure....(i)

Now, PoA = vapour pressure of pure solvent ...(ii)

The relative lowering of the vapour pressure is equal to ratio between...
Relative lowering of vapour pressure =x2 molefraction of solute. it's ratio of mole of solute -: mole of solute +mole of solvent (total molecules in the solution). if
solute present very minute amount then answer will 1
here answer is b.
