An open-end manometer constructed from a U-shaped tube was operated using an oil that has a density of 1.164 g mL⁻¹. In a particular measurement, the level in the end connected to the gas vessel, on which the experiment was being conducted, measured 82.8 cm above the U-neck, while the level in the open end was 17.2 cm above the U-neck. The outside air pressure in the laboratory was measured as 764 torr. What is the pressure in the gas vessel?Hint: The density of mercury is 13.533 g mL⁻¹^{at room temperature.}
