Question
1. Graham's Law: If 2.2x10-4 mol N2(g) effuses through a tiny hole in 105 s, then how much O2(g) would effuse through the same orifice in 105 s?
2. Use the ideal gas equation and van der Waals equation to calculate the pressure exerted by 1.00 mol Cl2(g) confined to a volume of 2.00 L at 273K. The value of constants: a = 6.49 L2-atm/mol2 and b = 0.0562 L/mol.

- If equal masses of O2 and N2 are placed in separate containers of equal volume at the same temperature, which of the following statements is true? If false, explain why it is false. (a) The pressure in the flask containing N2 is greater than that in the flask containing O2. (b) There are more molecules in the flask containing O2 than in the flask containing N2.arrow_forwardA sample of a smoke stack emission was collected into a 1.25-L tank at 752 mm Hg and analyzed. The analysis showed 92% CO2, 3.6% NO, 1.2% SO2, and 4.1% H2O by mass. What is the partial pressure exerted by each gas?arrow_forwardIn the text, it is stated that the pressure of 4.00 mol of Cl2 in a 4.00-L tank at 100.0 C should be 26.0 atm if calculated using the van der Waals equation. Verify this result, and compare it with the pressure predicted by the ideal gas law.arrow_forward
