Manometer

Q. A flask containing neon gas is connected to an open-ended mercury manometer. The open end is exposed to the atmosphere, where the barometric pressure is 745 torr. The mercury level in the open arm is 5.0 cm below that in the arm connected to the flask of neon. What is the neon pressure, in torr?

Manometer

Q. A mixture of nitrogen, helium, and neon gases is attached to an open manometer. The nitrogen exerts a pressure of 0.245 atm, and the helium exerts a pressure of 460. torr. If Patm=15.4 psi and the mercury level is 119 mm higher on the arm of the manometer open to the atmosphere, what is the pressure of the neon gas, in kPa?

Manometer

Q. A gas in enclosed in a 0.250 L container and exerts a pressure of 103.8 kPa. The gas is transferred to 3.75×105 mm3 flask that is attached to an open end manometer, where the Patm = 772 torr. In mm Hg, what will be the difference in height in the arms of the manometer? Assume that the temperature is constant.

Manometer

Q. A mercury manometer is connected on one side to a bulb containing argon, while the other end is open to atmospheric pressure, which is 763 mmHg. The mercury level in the open end of the manometer is 35 mm below that in the side connected to the argon (see figure below). What is the pressure of argon, in mmHg?

Manometer

Q. If the barometeric pressure was 0.99 atm when the mercury level in an open-end manometer connected to a flask of gas was 177 mmHg higher on the side open to the atmosphere than on the flask side, what was the pressure of the gas in the flask in torr? Enter your answer with two decimal places and no units. (Hint: sketch the apparatus.)
