vessel A was filled with enough air at 25 degree C to give a pressure of 50.0 torr. Vessel A has a volume of 675 ml. Vessel X, of Unknown volume, was connected to vessel A with a stopcock. Vessel X was empty initially (air had been evacuated), so its initial pressure was zero. The stopcock was opened allowing the air to expand at a constant temp and occupy both vessels. The final pressure for the entire system was 16.0 torr. What is the volume of vessel X? Please explain how you got an answer. thanks

I'm not solving it for you, but I'll tell you how to do it....
Use the equality: P1V1=P2V2
P1 is the initial pressure of 50.0 Torr
V1 is the initial volume of the container that the gas is in, 675 mL
P2 is the final pressure of the system, 16.0 Torr
V2 is the final volume of the system, Q
Now that you have the total volume of the system (Q) just subtract the volume of vessel A from total volume Q. This value will be the second vessel's volume.
If you don't understand the logic behind this, let me know.
