Which proportionality applies to avogadro’s law?

The volume of the gas is directly proportional and amount (moles) of the gas at constant T and P.

Explanation:

Avogadro's law states that, "equal volumes of all gases, at the same temperature and pressure, have the same number of molecules."For a given mass of an ideal gas, the volume of the gas is directly proportional and amount (moles) of the gas at constant T and P.V ∝ n.

Both models are effective because they show the valence electrons, and these valence electrons indicate the reactivity of an element.
