PART C: A cubical box 1.00 mm on a side contains air at 20.0∘C∘C. What would the pressure inside the box have to be in order for the mean free path of air molecules (assumed to be spheres of radius 2.0×10−10m2.0×10−10m) to be 1.00 mm, so that a typical molecule suffers no collisions with other molecules as it travels the width of the box?

PART D:

How many moles of air would be inside the box at the pressure calculated in part C? (At 1 atm pressure, this box would contain 41.4 mol of air.)
