According to the ideal gas law, a 0.9054 mol sample of krypton gas in a 1.023 L container at 274.0 K should exert a pressure of 19.90 atm. What is the percent difference between the pressure calculated using the van der Waals' equation and the ideal pressure? For Kr gas, a = 2.318 L2atm/mol2 and b = 3.978×10-2 L/mol. % According to the ideal gas law, a 9.344 mol sample of oxygen gas in a 0.8267 L container at 500.1...

1.Effusion is a process in which a gas escapes from a container through a small opening into a vacuum. In a pair of experiments, a sample of tetrafluoroethylene, C2F4, effuses at a rate of 4.6 × 10-6 mol/h and an unknown gas effuses at a rate of 4.0×10-6 mol/h. Identify the unknown gas. 2.Molecules in a sample of a gas move at a variety of speeds. Molecular speed can be described by the root-mean-square speed of the gas, which is...

Which of the following statements is true for real gases? Choose all that apply Attractive forces between molecules cause a decrease in pressure compared to the ideal gas. Attractive forces between molecules cause an increase in pressure compared to the ideal gas. As molecules increase in size, deviations from ideal behavior become more apparent at relatively low pressures. As attractive forces between molecules increase, deviations from ideal behavior become more apparent at relatively low temperatures. Compute the root-mean-square speed of...
