Answer:
Concentration and its implications remain very important from the initial stages of chemistry all the way through the most advanced concepts. Concentration conceptually is very important for two, of many, reasons.
First: concentrations are used for chemical reactions. It tells you how much you have, in how much volume. Without concentrations it's like trying to make a recipie without amounts. A chemical reaction that requires specific amounts of reagents may just not work without the proper concentrations. To work through a replicatable chemical reaction, you have to know concentration. In some cases not knowing can even be dangerous, as not knowing the concentration of some reagents can incur risk with strong acids and bases. Another great example is pharmaceuticals. Concentration is very important, and is related to the prescribed dosage of medicine. The wrong concentration (think of the body as the solvent!) can be a serious issue.
A second major reason is related to chemical testing. Concentration is directly tied to determining information like how much heavy metal is in water, or how much pesticide ran off into a nearby water source, or how strong an instance of acid rain is. The list goes on. Without concentration usage, these types of analysis would be much more difficult or even impossible.
