Suppose that a sample of gas occupies 187 mL
of volume at 298 K and a pressure of 277 torr.
What would be the volume (expressed of
this sample) if the pressure were changed to
571 torr at 298 K?
Answer in units of mL.

Answer:
V2 = 90.7 mL
Explanation:
pressure and volume are inversely proportional, if the pressure is increased, the volume will decrease. In an isothermal process:
p1V1 = p2V2
V2 = p1V1/p2 = (277 torr×187 mL)/571 torr
V2 = 90.7 mL
