SUMMARY
The discussion focuses on calculating the spacing between atoms of an ideal gas at a temperature of 273K and a pressure of 1 atm using the mean free path equation. Participants clarified that the mean free path equation, ʎ = 1 / 4(pi)(n)(σ²), can be utilized without needing the exact radius of the atom, which is approximately 0.1 nm. The calculated atomic spacing is around 3 nm, significantly larger than the atomic radius. The conversation also touches on the distinction between mean free path and atomic spacing, emphasizing that atomic size is negligible compared to the spacing.
