Two liquids A and B are mixed at temperature T in a certain ratio to form an idela solution. It is found that the partial vapoure pressure of A. i.e, P_(A) is equal to P_(B) . The vapoure pressure of B for the liquid mixture. Whatis the total vapour pressure of the liquid mixture in terms of P_(A)^(@) and P_(B)^(@) ?

Vapor pressure of a solution of Volatile components and composition of vapor: Consider a solution containing 738 g of water and 253 g of ethanol (C_(2)H_(5)OH) at 323 K . At this temperature, the vapour pressure of pure ethanol is 0.292 atm and the vapor pressure of pure water is 0.122 atm . Calculate the vapour pressure of the solution and mole fraction of every component in vapour phase. Strategy: First calculate the moles and the mole fraction of each component in the liquid solution. Then apply Raoult's law to each of the two volatile components to calculate their partial pressures. The total vapour pressure is the sum of the partial vapour pressures of the components and the mole fraction of a components in a gaseous mixture equals the ratio of its partial pressure to the total pressure.
