Question

state approximate space between two molecules

Answer 1

So, the average spacing, using your teacher's method, is about ( 2.5 × 10 25 ) − 1 / 3 = 3.4 nm. The radius of molecular nitrogen is 0.2 nm. So, the diameter is about 0.4 nm. The means that only about ( 0.4 / 3.4 ) 3 = 0.0016 of the volume of air is filled withmolecules
