A cylinder for storing helium (molar mass 4.00 g/molg/mol) has an interior volume of 50.0 L=5.00×10−2m3L=5.00×10−2m3. The cylinder holds 4.00×102mol4.00×102mol of helium under pressure at 27.0∘C∘C. If you assume the helium atoms are spheres of radius 3.1×10−11m3.1×10−11m what is the mean free path of a helium atom in the tank?
What is the mean free time for a helium atom moving at the rms speed?
