Plate A = filter paper dipped into 5% solution of unknown Dye A Plate B = filter paper dipped into 5% solution of unknown Dye B Both plates were incubated at 37°C. At the end of the 60 minute incubation period the diffusion rings for each dye were measured. The diffusion ring for Dye A = 40 mm. The diffusion ring for Dye B 24 mm Based on the results, which dye had the higher molecular weight? Explain your answer.

Question
**Experiment on Diffusion and Molecular Weight** *Materials Used:* - **Plate A**: Filter paper dipped into a 5% solution of unknown Dye A - **Plate B**: Filter paper dipped into a 5% solution of unknown Dye B *Method:* Both plates were incubated at 37°C. After a 60-minute incubation period, the diffusion rings for each dye were measured. *Results:* - Diffusion ring for Dye A = 40 mm - Diffusion ring for Dye B = 24 mm *Discussion:* Based on these results, which dye had the higher molecular weight? Explain your answer. **Explanation:** Generally, substances with a lower molecular weight diffuse faster and further than those with a higher molecular weight. In this experiment, Dye A diffused further (40 mm) compared to Dye B (24 mm). This suggests that Dye B has a higher molecular weight than Dye A.
