Concentration
Definition
Concentration refers to the amount of a substance (solute) present in a certain volume of solution.
Analogy
Imagine you're making lemonade. The more lemons you squeeze into the water, the stronger (more concentrated) your lemonade will be. If you only squeeze one lemon into a gallon of water, it's going to taste pretty weak (less concentrated).
