The statement “the relative lowering of the vapour pressure Is equal to the ratio of the molecules of the solute to the total number of the molecules In the solution” refers to _______

Derive an expression for the relative lowering of vapour pressure?

The relative lowering of vapour pressure of an aqueous solution containing non - volatile solute is 0.0125 . The molality of the solution is

Why is the vapour pressure of a solvent lowered by the ạddition of a non- volatile solute?

Lowering of vapour pressure in 1 molal aqueous solution of non volatile non electrolyte solute at 100^@C is:

The solution having highest vapour pressure is :(Assume 100% ionisation of electrolytes)

Relative lowering of vapour pressure, elevation of boiling point, depression of freezing point and osmotic pressure are important colligative properties of dilute solutions. Relative lowering of vapour pressure of an aqueous dilute solution of glucose is 0.018 What is the mole fraction of glucose in the solution ?
