The volume of a manifold used to transfer gases is calibrated using Boyle's Law. A 0.251-dm3 flask at pressure of 697 Torr is attached and after system pumpdown, the manifold is at 10.4 mTorr. The stopcock between the manifold and the flask is then opened and the system reaches an equilibrium pressure of 287 Torr. Assuming isothermal conditions, what is the volume of the manifold?
