A closed-end manometer that utilizes an oil having a density of 0.820 g ml⁻¹ is being used to measure gas pressure in a vessel designed for studies on the gaseous state. In a particular experiment, the oil in the closed end of this manometer was 62.2 cm above the U-neck, while the level in the end connected to the vessel was measured as 25.2 cm above the U-neck. What is the pressure, in atmospheres, of the gas?Hint: The density of mercury is 13.533 g mL⁻¹^{at room temperature.}
