Assuming the radius of diatomic molecules is approximately 1.0  10-10 m, for what pressure will the mean free path in room-temperature (20C) nitrogen be 4.6 m?
 
  The Boltzmann constant is 1.38  10-23 J/K, Avogadro's number is 6.02  1023 molecules/mole, and the ideal gas constant is R = 8.314 J/molK = 0.0821 L  atm/mol  K.
  A) 4.9  10-8 atm
  B) 6.9  10-8 atm
  C) 1.5  10-7 atm
  D) 2.2  10-7 atm

Question 2

What is the mean free path of a gas of randomly-moving hard spheres of radius 2.00  10-9 m when the density of spheres is 3.00  1019 per cubic meter?
 
  A) 1.17  10-4 m
  B) 4.00  10-9 m
  C) 9.76  10-5 m
  D) 1.88  10-3 m
  E) 4.69  10-4 m
