Vapour pressure (in torr) of an ideal solution of two liquids and is given by : where is the mole fraction of in the mixture. The vapour pressure (in torr) of equimolar mixture of the two liquids will be :
The vapour pressure (at the standard boiling point of water) of an aqueous solution containing by mass of a non-volatile normal solute (molecular mass = 28) will be
A solution at is composed of of benzene and of toluene. If the vapour pressure of pure benzene and pure toluene at this temperature are torr and torr, respectively, then the total vapour pressure of the solution and the benzene mole fraction in equilibrium with it will be, respectively :
For an ideal solution of two components and B, which of the following is true?
100 mL of liuqid 'A' was mixed with 25 ml of a liquid 'B' to give a non-ideal solution of A-B mixture showing (-) ve deviation from Raoult's law. The volume of this mixture would be
