SUMMARY
The average distance between gas molecules can be calculated using the ideal gas law, represented by the equation PV = nRT, where P is pressure in torr, V is volume in cm³, n is the number of moles, R is the ideal gas constant, and T is temperature in Kelvin. The number of molecules (N) is derived from the number of moles multiplied by Avogadro's number (N = n * NA). To find the average distance between molecules, one can determine the volume occupied by each molecule (V/N) and consider it as a sphere, leading to the conclusion that the average distance is related to the cube root of the volume per molecule.
