Additional recommended knowledge
One form of the Lorentz-Lorenz formula (also known as the Clausius-Mossotti equation) gives the molar refractivity of a dilute gas as
In SI units, R has units of J mol-1 K-1, T has units K, n has no units, and p has units of Pa, so the units of A are m3 mol-1. Therefore, the molar refractivity is the volume of the substance (in cubic meters) taken up by each mole of that substance.
