You use the air from a compressed air tank with a volume of 10 liters and an initial gauge pressure of 180atm (measured
at the surface) to fill the balloon. The balloon is initially empty and you fill it at depth right near the tock. What will be the
absolute preesure in tank once you extracted all the air needed to inflate the balloon to the volume of 307liter? Assume
the temperatuer is constant and the same everywhere. The answer is 31 atm and I don't understand how.

This device consists of a glass bulb forming one end of a beam, the whole surrounded by a closed container. The beam is pivoted, and the balance point is attained by raising the pressure of gas in the container, so increasing the buoyancy of the enclosed bulb. In one experiment, the balance point was reached when the fluorocarbon pressure was 327.10 Torr; for the same setting of the pivot, a balance was reached when CHF, (M= 70.014g mol) was introduced at 423.22 Torr. A repeat of the experiment with a different setting of the pivot required a pressure of 293.22 Torr of the fluorocarbon and 427.22 Torr of the CHF,. What is the molar mass of the fluorocarbon?
