Relatives lowering of vapour pressure

STATEMENT-1 : Relative lowering of vapour pressure is equal to mole fraction of the solute. and STATEMENT-2 : Relative lowering of vapour pressure is a colligative property.

Statement-I: Relative lowering of vapour pressure is equal to mole fraction of the solvent. Because Statement-II: Relative lowering of vapour pressure is a colligative property.

A: Lowering of vapour pressure depends upon concentration of solute. R: Relative lowering of vapour pressure is a colligative property

Relative lowering of vapour pressure of a solution containing a non volatile solute (X) in a solvent (Y) is 3%. What is the mole percentage of component 'Y' in the solution.

Assertion (A): Vapour pressure of 0.5 M sugar solution is more than 0.5 M KCl solution. Reason (R): Relative lowering of vapour pressure is directly proportional to the number of species present in the solution.

Relative lowering of vapour pressure , osmotic pressure of a solution and elevation in boiling points are __(p)___ properties. Osmosis is the passage of __(q)__ through a semipermeable membrane from a solution of __(r)__ towards a solution of __(s)__ . Osmotic pressure is equivalent to mechanical pressure which must be applied on __(t)__ to prevent osmosis. In the above paragraph p,q,r,s and t respectively are
