We’re being asked to determine the pressure of a gas (in atm, torr, and Pa) using an open-end manometer.
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).
Different conditions for an open-end manometer are illustrated below:
• When Pgas is pushing the same force as Patm
• When Pgas is pushing harder than Patm
A diagram for an open-tube manometer is shown below.
If the flask is open to the atmosphere, the mercury levels are equal. For each of the following situations where a gas is contained in the flask, calculate the pressure in the flask in torr, atmospheres, and pascals.
