What is the pressure in atmospheres inside a container of gas connected to a mercury-filled open-end manometer when the level in the arm connected to the container is 23.6 cm higher than the level in the arm open to the atmosphere andthe atmospheric pressure reading outside the apparatus is 1.011atm ? Express your answer using three decimal places. What is the pressure of the gas in mm Hg inside the apparatus shown if the outside pressure is744mm Hg ?(Figure 1) figure shows 25 cm What is the pressure in atmospheres in a container of gas connected to a mercury-filled, open-end manometer if the level in the arm connected to the container is 28.5 cm higher than in the arm open to the atmosphere and atmospheric pressure is 0.992atm ?

Explanation / Answer

2...

744mm - 760mm(1 atm) =- -16mm

25cm = 250mm

250 mm - 16mm = 234 mmHg of pressure

That is gauge pressure. If you want to include atmospheric pressure add 760mmHg to it.
