Three cylindrical flasks A, B and C of diameter 50 mm, 75 mm and 100 mm, respectively have graduation marked in mm and are used for measurement of volume of liquid. Which of the following statement is correct?

One mole of liquid A (vapour pressure =300 mm Hg ) and 2 moles of a liquid B (Vapour pressure =360 mm Hg) are mixed . The mole fraction of A in the vapour mixture if found to be 5//17 . Which of the following is correct ?

Consider the adjacent diagram. Initially, flask A contained oxygen gas at 27^(@)C and 950 mm of Hg , and flask B contained neon gas at 27^(@)C and 900 mm . Finally, two flask were joined by means of a narrow tube of negligible volume equipped with a stopcock and gases were allowed to mixup freely. The final pressure in the combined system was found to be 910 mm of Hg . Which of the following statements concerning oxygen and neon gas is true in the begining, when the stopcock was just opened?

At 300 K, two pure liquids A and B have vapour pressures 150 mm Hg and 100 mm Hg respectively. In an equimolar liquid mixture of A and B, the mole fraction of B in the vapour mixture at this temperature is:
