How is molarity calculated for a solution?

• A. Volume of solution divided by mass of solute
• B. Number of moles of solute divided by volume of solution in liters
• C. Moles of solute multiplied by volume of solution
• D. Mass of solute divided by molar mass

Answer: (B)

Molarity is defined as the concentration of a solution expressed as the number of moles of solute per liter of solution. It provides a way to quantify how much solute is present in a given volume of solvent. The correct calculation of molarity involves taking the number of moles of solute—the amount of substance measured in moles—and dividing that by the volume of the solution measured in liters. This relationship is fundamental in chemistry because it allows for precise calculations in reactions, dilutions, and when preparing solutions. By providing a standard way to express concentration, molarity becomes a crucial concept for students to understand when working with solutions in various chemical contexts.
