@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 0.7242 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 1209.72 cm?

@X@user.full_name@X@ @GMU: A flexible container was filled with N2O4 gas at a pressure of 1.629 atm and volume of 10.052 L. What volume would this same gas occupy if the pressure increased to 3.435 atm? Assume temperature is constant.

@X@user.full_name@X@ @GMU: The density of a particular gas is 2.7702 g/L at 827.04 mm Hg and 33.54 °C. What is the molecular mass of the gas?

@X@user.full_name@X@ @GMU: The density of a particular gas is 3.5345 g/L at 818.12 mm Hg and 27.15 °C. Which gas is it?

@X@user.full_name@X@ @GMU: A flexible container was filled with 0.1503 mol of CO at a volume of 16.20 L. How many moles of this gas would there be if the volume decreased to 8.48 L? Assume pressure is constant.
