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 1.0*10^-10 torr. a)calculate the molar density at this pressure at 310. bwhat fraction of the gas phase molecules initially present for 1.0 in the chamber are present at ?

The diagram below shows a cell placed in a solution.a cell is shown placed inside a beaker. it is labeled cell. the solution inside the beaker is labeled 40% salt solution and the solution inside the cell is labeled 20% salt solution.only water is allowed to move in and out of the cell. what will most likely happen to the cell? it will expand as water moves out of it. it will shrink as water moves out of it.it will expand as water moves into it. it will shrink as water moves into it.
