A manometer allows you to determine the pressure of a gas (Pgas) sample by using the atmospheric pressure (Patm) and the difference in the height of mercury (h).

When Pgas is pushing harder than Patm

Problem Details

If the atmospheric pressure is 0.980 atm , what is the pressure of the enclosed gas in each of the three cases depicted in the drawing Diagrams (i) to (iii) show an apparatus consisting of a gas flask on the left attached to a U-shaped tube of mercury with an open end at the right; in part (iii), the tube is closed at the end. The height of the mercury varies for each gas. In (i) the left side is higher, but in (ii) and (iii) the right side is higher.?

What is the pressure of the enclosed gas in (i)? Assume that the gray liquid is mercury.
