Many processes such as the fabrication of integrated circuits are carried out in a vacuum chamber to avoid reaction of the material with oxygen in the atmosphere. It is difficult to routinely lower the pressure in a vacuum chamber below 9.0 x10¹¹ Torr. Part B Correct What fraction of the gas phase molecules initially present for 1.0 atm in the chamber are present at 1.0 x 10-10 Torr? Express fraction to two significant figures.
