What is the relationship between the density of a substance and its atomic/molecular weight?
That makes sense. Are there any exceptions to this relationship?
There are some exceptions to this relationship due to the specific arrangements of molecules in different substances. For example, the density of ice is lower than that of liquid water, even though ice has a higher molecular weight. This is due to the unique arrangement of molecules in ice, which causes it to be less dense.
