Methylene blue‚ having the largest molecular weight‚ displayed the smallest diameter (18 mm) and diffused at the slowest rate (0.3668 mm/min.). Thus‚ the higher the molecular weight‚ the slower the rate of diffusion. INTRODUCTION A substance in the gaseous or liquid state consists of molecules or atoms that are independent
