If the pressure of 8.0 L of nitrogen gas in a flexible container is decreased to one-fifth of its orginal pressure(at constat teperature)' the volume will now be ?

  • Chemistry -

    Use Boyle's Law.

    P*V = constant

    P1 = initial pressure
    P2 = final pressure = P1/5
    V1 = initial volume = 8 L
    V2 = final volume

    (8 L)*P1 = V2*(P1/5)
    P1 cancels out

    V2 = 40 L
