Solution:
Benzoic acid, C6H5COOH, melts at 122 oC. The density in the liquid state at 130 oC is 1.08 g/cm3. The density of solid benzoic acid at 15 oC is 1.266 g/cm3.
In which of these two states is the average distance between molecules greater?

Problem

Benzoic acid, C6H5COOH, melts at 122 oC. The density in the liquid state at 130 oC is 1.08 g/cm3. The density of solid benzoic acid at 15 oC is 1.266 g/cm3.

In which of these two states is the average distance between molecules greater?

Solution
  • The density is the relationship between the mass of the substance and how much space it takes up (volume). 

  • Density is related to the distance between the molecules where denser substances will appear to have compact volume. This tells us that the distance between molecules are shorter compared to less dense substances.
