Define solubility. Name the factors on which solubility of a solute in a solvent depends.

The vapour pressure of the solvent decreased by 10 mm of Hg when a non volatile solute was added to the solvent. The mole fraction of the solute in the solution is 0.2. What should be the fraction of the solvent if a decrease in vapour pressure of 20 mm of Hg is desired:

The two solutions A and B are separated by semipermeable membrane. If the solvent flows from A to B :

Give reasons : Alkyl halides are better solvents than aryl halides.
