1. Calculate the root square mean velocity of Cl2 at 25 ºC.
2. An Unknowngas effuses at a rate that is 0.462 times that of nitrogen gas (atthe same temperature). Calculate the molar mass of the unknown gasin g/mol.
3. A gasmixture contains 1.28 g N2 and 0.85 g O2 in a1.55 L container at 18 ºC. Calculate the mole fraction and partial pressure of each gas component in the gas mixture.
4. What is the pressure in a 10.0 L cylinder filled with 0.448 mol of nitrogen gas at a temperature of 42 ºC?
