Question

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
