The average space between molecules is about 30 angstroms or 3 nm.
Explanation:
Atomic spacing refers to the distance between the nuclei of an atoms in a material.This space is large compared to the size of atomic nucleus and is related to the chemical bonds which binds together.
The Atomic spacing is defined by using laws of diffraction and by passing electromagnetic waves called frequency through the material.
Gas is a state of matter that has no fixed shape and no volume.
