The pressure of the confined gas will be 769-17 = 752 mmHg
<h3>What is Manometer ?</h3>
Manometer is a U shaped instrument which is used to measure the pressure acting on a column of fluid , a difference in the pressure in the two arms of the manometer causes the liquid to reach different heights.
The difference in the heights of the Hg columns in Diagram B is17 mm-Hg.
the atmospheric pressure is 769 mm-Hg,
