Derive an expression for the relative lowering of vapour pressure?

Assertion : Lowering of vapour pressure is not dependent on the number of species present in the solution. Reason : Lowering of vapour pressure and relative lowering of vapour pressure are colligative properties. a)If both (A) and (R) are correct and (R) is the correct explanation of(A). b)If both (A) and (R) are correct, but (R) is not the correct explanation of (A). c)If (A) is correct, but (R) is incorrect. d)If both (A) and (R) are incorrect.

Equal weight of a certain non volatile non electrolyte solute is dissolved in equal weight of two solvents A and B to form very dilute solution. The relative lowering of vapour pressure for solution B is twice the relative lowering ofvapour pressure for solution A. M_A and M_B are the molecular mass of solvents A and Brespectively, then: a)M A = M B b)M B = 2 × M A c)M A = 4 M B d)M A = 2 M B

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 ?

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 _______
