Question
A chemist takes four samples of a substance. Each sample has a different density. What can the chemist conclude about the substance?
Solution
The chemist can conclude that the substance is not pure. In a pure substance, the density remains consistent across all samples. The variation in density suggests that the substance is a mixture of different materials, each with its own unique density. This could be due to differences in composition, temperature, pressure, or other factors. The chemist would need to conduct further tests to determine the exact cause of the density variations.
