uranium. Gas effusion was used because the density of the hexachloride made from uranium-235 is 2.2920 g/L at 16 kPa and 20 C while under the same conditions the density of the hexafluoride made from uranium-238 is 2.3119 g/L. (In the gaseous states, these compounds behave remarkably like ideal gases.)

Graham's Law of Effusion Problems 1-10. Probs 11-25. Ten Examples. Examples and Problems only. Return to KMT & Gas Laws Menu. Problem #1: If equal amounts of helium and argon are placed in a porous container and allowed to escape, which gas will escape faster and how much faster? Solution: 1) Set rates and get atomic weights:
This difference in density, in the light of Graham's law, suggests a potential problem in using natural gas pipelines for sending hydrogen if we should ever adopt hydrogen as an alternative fuel to methane. What is this problem? Compare the rate of effusion of hydrogen to the rate for methane.
The effusion rate of an unknown gas is measured and found to be 31.50 mL/min. Under identical experimental conditions, the effusion rate of O2 is found to be 30.50 mL/min.
