@X@user.full_name@X@ @GMU: Assume you have an open ended manometer filled with an oil having a density of 0.7901 g/mL at 20°C rather than mercury (density = 13.546 g/mL at 20°C). What is the pressure in atmospheres if the level of the arm open to the atmosphere is 126.82 cm lower than the level in the arm connected to the gas sample? The atmospheric pressure reading is 756.62 mm Hg.
