Have you ever made a glass of Kool-Aid or lemonade and found it too sweet or too weak? That’s concentration in action! In chemistry, concentration tells us how much solute (the substance dissolved) is present in a given volume of solution. It’s like the strength of your drink, more solute means a more concentrated solution! We measure this strength in mol dm⁻³ (moles per cubic decimetre).
