Two bulbs are separated by a stopcock valve. one contains helium at a pressure of 4.40 atm. the other contains krypton at a pressure of 1.75 atm. after the stopcock has been opened, the total pressure measured in the two connected bulbs is 3.52 atm. if the mole fraction of helium at the final state is 0.83, how much larger or smaller is the bulb that initially contains the krypton (i. e. what is the ratio of the two bulbs' volumes)? assume ideal gas behavior and a constant t.
