Question

An urgent physical chemistry question!!!!

1A 4 The molar mass of a newly syntbesized 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 buuyancy 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 halance was reached when
CHE, (M= 70.014g mol") was introduced at 423.22 Torr. A repeat of the
experiment with a different setting of the pivot required a presure of 293 22
Torr af the fluorocarbon and 427.22 Torr of the CHF, What is the malat mass
of the fluorocarbon? Suggest a molecular formula.
