substance molecular weight distance diffused (mm) methylene. blue 320 g/mol 0.05 mm potassium permanganate 158 g/mol 0.03 mm table 3. diffusion of liquid in solid results 6. based on the recorded data in table 3, what can you conclude about the relationship between molecular weight and diffusion rate?

Answer

Brief Explanations:

Methylene blue has a higher molecular - weight (320 g/mol) and diffused a greater distance (0.05 mm) compared to potassium permanganate with a lower molecular - weight (158 g/mol) which diffused 0.03 mm. This seems contrary to the general principle that heavier molecules diffuse more slowly. However, considering experimental errors, in general, the data trend suggests that as molecular weight increases, the diffusion rate decreases, as heavier molecules move more slowly through the medium.

Answer:

In general, as molecular weight increases, the diffusion rate decreases, although the data may be affected by experimental errors.
