Calculate the pressures, ? , in atmospheres at which the mean free path, ? , of a hydrogen molecule will be 1.50 μm , 1.50 mm , and 1.50 m , respectively, at 20.0 ∘C . The diameter of a H2 molecule is 270 pm .
The mean free path is the average distance a molecule travels before colliding with another molecule....
The mean free path is the average distance a molecule travels before colliding with another molecule. The mean free path, λ, is given by ? = ??/ radical(2)?? , where k is Boltzmann’s constant, T is temperature (K), P is pressure (Pa), and σ is the collision cross section. For a molecule with a diameter d, the collision cross-section is πd2. The collision cross section is the area swept out by the molecule within which it will strike any other...

A nitrogen molecule has a diameter of about 0.29 nm. The mean free path of a nitrogen molecule in a tank of dry nitrogen at room temperature (293 K) and standard pressure (1 atm) is about 0.10 µm. A tank containing nitrogen at standard temperature (273 K) and pressure has volume V. If the tank is compressed by means of a piston to 20% of its original volume, what is the mean free path for a nitrogen molecule under the...
