If Avogadro's number were to tend to ∞, the phenomenon of Brownian motion would — States of Matter and Gaseous State Chemistry Question

💡 Solution & Explanation

if avogadro's number n_a → ∞, the mass of individual gas molecules (m = m/n_a) would tend to 0 while their number density would tend to ∞. at any instant, the number of molecular collisions on opposite sides of a brownian particle would become extremely large, and the random statistical imbalances (which cause brownian motion) would completely average out to zero. thus, brownian motion would become practically unobservable.
