Final answer:
Concentration, specifically molarity, is measured in mol/dm³, and it represents the number of moles of solute per liter of solution in chemistry.
Step-by-step explanation:
The quantity measured in mol/dm³ is known as concentration, specifically molarity. This unit of measurement is utilized in chemistry to express the number of moles of solute present in exactly one liter (dm³) of solution. The formula to calculate molarity (C) is given by C = n/V, where 'n' is the number of moles of solute and 'V' is the volume of solution in cubic decimeters (dm³). Molarity is a critical concept in the study of solutions, enabling chemists to quantify the exact amount of a substance dissolved in a solution.
