A closed end mercury manometer is being used to measure gas pressure in a manifold designed for studies on the gaseous state. In a particular experiment, the mercury in the closed end of this manometer was 62.2 cm above the U-neck, while the level in the open end (connected to the manifold) was measured as 25.2 cm above the U-neck. What is the pressure, in torr, in the gas collection manifold?
