Camphor is used as solvent to determine molecular weight of non-volatile solute by Rast method because. For camphor:

Which of the following methods can not be used to determine the molecular weight of non-volatile solute?

How can you determine the molecular mass of a non-volatile solute from elevation of boiling point ?

How is osmotic pressure related to molecular weight of solute?

How can you determine the molecular mass of a non-volatile solute from depression of freezing point ?

How does vapour pressure of a solvent affected by adding a non-volatile solute to it?

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