At 40^@C the vapour pressures of pure liquids, benzene and toluene, are 160 mm Hg and 60 mm Hg respectively. At the same temperature, the vapour pressure of an equimolar solution of the two liquids, assuming the ideal solution should be:

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:

The vapour pressure of a solution of a non-volatile electrolyte (B) in a solvent (A) is 95% of the vapour pressure of the solvent at the same temperature. If the molecular weight of the solvent is 0.3 times the molecular weight of solute, the weight ratio of the solvent and solute are:

Vapour pressure of pure solvent is 0.8 mm of Hg at a particular temperature. On addition of non volatile solute ‘A’ the vapour pressure of solution become 0.6 mm of Hg. The mole fraction of component ‘A’ is –
