P1A.6 The molar mass of a newly synthesized fluorocarbon was measured
in a gas microbalance. 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? Suggest a molecular formula.
