At a certain temperature molecules of methane gas CH_4 have an average velocity of 0.098 m/s. What is the average velocity of carbon dioxide molecules at this same temperature? Find the relative rate of diffusion for the gases chlorine, Cl_2 and ethane, C_2H_6. 495 cm^3 of oxygen gas and 877 cm^3 of nitrogen gas, both at 25.0 degree C and 114.7 kPa, are injected into an evacuated 536 cm^3 flask. Find the total pressure in the flask, assuming the temperature remains constant. A sample of gas is transferred from a 75 mL vessel to a 500.0 mL vessel. If the initial pressure of the gas is 145 atm and if the temperature is held constant, what is the pressure of the gas sample in the 500.0 mL vessel? A sample of gas occupies a volume of 450.0 mL at 740 mm Hg and 16 degree C. Determine the volume of this sample at 760 mm Hg and 37 degree C.
