It took 4.5 minutes for 1.0 L of helium to effuse through a porous barrier. How long will it take for 1.0 L of Cl2 gas to effuse under identical conditions?

## Answer to relevant Questions

Calculate the pressure exerted by 0.5000 mole of N2 in a 1.0000- L container at 25.0oC. (See Table) a. Use the ideal gas law. b. Use the van der Waals equation. c. Compare the results from parts a and b. Table In the van der Waals equation, why is a term added to the observed pressure and why is a term subtracted from the container volume to correct for nonideal gas behavior? Consider separate 1.0- L samples of O2(g) and He(g), both at 25oC and the same pressure. Compare the change in momentum per impact and the number of impacts per second in the two samples. A form of Boyle’s law is PV = k (at constant T and n). Table contains actual data from pressure– volume experiments conducted by Robert Boyle. The value of k in most experiments is 14.1 × 102 in Hg in3. Express k in ...The total mass that can be lifted by a balloon is given by the difference between the mass of air displaced by the balloon and the mass of the gas inside the balloon. Consider a hot-air balloon that approximates a sphere. ...Post your question
