a barometer is read directly in torrs or mm Hg. an open-end manometer has a closed arm liquid height of 48.4 mm and an open arm liquid height of 62.6 mm. if the air pressure is 758.0 torrs, what is the pressure of the gas connected to the manometer?

1 answer

The difference is 62.6-48.4 = 14.2
So the closed end is higher pressure than the open end so 758-14.2 = P closed end.
