What is indicated by the Ideal Gas Constant being the same value for all gases in Avogadro's Law?

The Ideal Gas Constant being the same value for all gases in Avogadro's Law indicates that gas behavior is consistent across all types. This means that under similar conditions of temperature and pressure, different gases will exhibit similar behaviors concerning volume when the number of moles of gas is held constant. The Ideal Gas Law, which is defined as PV = nRT, shows that for any ideal gas, the relationship between pressure (P), volume (V), temperature (T), and the number of moles (n) of gas adheres to this consistent value of the Ideal Gas Constant (R).

This uniformity under Avogadro's Law suggests that all gases occupy the same volume per mole at the same temperature and pressure, exemplifying their predictable and comparable nature regardless of their chemical identity. While individual gases may differ in molecular weights, that does not affect the fundamental behavior described by the Ideal Gas Law across all gases.
