An open-end mercury manometer was constructed from a U-shaped tube and connected to a gas container. In a particular measurement, the level in the end of the tube connected to the gas container measured 76.2 cm above the U-neck, while the level in the open end (to the atmosphere)was 23.8 cm above the U-neck. The outside air pressure in the laboratory was measured as 754 torr. What is the pressure in the gas container?
