Q Question 1 1 / 1 pts A 8.0 L vessel contains gases that have a total pressure of 750.8 mm Hg. The vessel contains 0.439 mol of oxygen gas, 0.371 moles of nitrogen gas, and 0.117 moles of carbon dioxide gas. What is the pressure (in mm Hg) of the nitrogen gas in the vessel? Question 2 1 / 1 pts A gas sample with a volume of 38.5 L has a pressure of 527 mm Hg at 20.8 °C. What is the pressure of the sample if the volume remains at 38.5 L but the temperature rises to 50.7 °C? Question 3 1 / 1 pts A cylinder with a moveable piston contains 176 mL of nitrogen gas at a pressure of 1.58 atm and a temperature of 283 K. What must the final volume be for the pressure of the gas to be 1.26 atm at a temperature of 331 K? Question 4 1 / 1 pts 2.31 atm of a gas has a density of 1.75 g/L at 302° C. What is the molar mass of the gas? Question 5 1 / 1 pts A gas in a sealed container at 177.3 K has a pressure of 263.3 mm Hg and a volume of 21.4 L. How many moles of gas are in the container?
