I have looked up multiple definitions and they still seem the same to me. Can anyone help a non-science person wrap my head around the concept?
In: Chemistry
There isn’t a difference. We use the word ‘concentration’ when there are other substances around. I.e. if a block of salt was standing in a vacuum we would talk about its density, and if we dissolve salt in water we would talk about its (now much lower) concentration. The essence of the number (amount / volume) is identical.
