Two moles of pure liquid 'A' ($$P^o_A$$ = 80mm of Hg) and 3 moles of pure liquid 'B' ($$P^o_B$$ = $$120$$mm of $$Hg$$) are mixed. Assuming ideal behaviour.

Two flasks of equal volume have been joined by a narrow tube of negligible volume. Initially, both flasks are at 300K containing 0.6 mole of $$O_2$$ at 0.5 atm pressure. one of the flasks is placed in the thermostat of 600K. FInd the number of mole of $$O_2$$ gas in each flask.
