    This was posted by someone else and somone replied saying

    p1v1=p2v2 where (2)(.8)=(1.6)(x)

    and it does give the right answer.

    why 1.6 for the new volume?
    How does injecting the 400ml bring down the volume from 2 liters??


    1. Into a two liter vessel, containing a gas at 0.8 atmospheric pressure, 400mL of mercury is injected. What would be the new pressure? (There is no evidence of a chemical reaction)

    The answer is 1atm. Can somebody explain how to get 1atm?
