@X@user.full_name@X@ @GMU: The density of a particular gas is 5.7440 g/L at 812.98 mm Hg and 24.80 °C. What is the molecular mass of the gas?

@X@user.full_name@X@ @GMU: Closed-tube manometers work exactly as barometers except by connecting them to a container its pressure can be measured. Assume you have a closed-ended manometer filled with an oil having a density of 0.7722 g/mL at 20°C rather than mercury (density = 13.546 g/mL at 20°C). What is the pressure if the height of the oil column is 1094.62 cm?
