One litre flask contain air, water vapour and a small amount of liquid water at a pressure of 200 mm Hg. If this is connected to another 1L evacuated flask, what will be the final pressure of the gas mixture at equilibrium? Assume the temperature to be 50^(@)C. Aqueous tension at 50^(@)C = 93 mm of Hg

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 . If flask B were heated to 127^(@)C , maintaining flask A at constant temperature of 27^(@)C , final pressure (in mm Hg ) in the combined system would have been
