Which formula represents the relationship between molarity and volume?

The formula that accurately represents the relationship between molarity and volume is M1V1 = M2V2. This equation is derived from the concept of dilution, which is commonly encountered in chemistry and industrial practices.

In this formula, M1 and V1 denote the molarity and volume of the initial solution, while M2 and V2 represent the molarity and volume of the diluted solution after the initial solution has been diluted with a solvent. The relationship highlights that the product of the initial molarity and volume equals the product of the diluted molarity and volume, reflecting the conservation of solute during the dilution process.

This makes it easy to calculate the concentration of a solution after a specific amount of solvent has been added, which is a vital skill in various industrial and laboratory settings where precise concentrations are crucial for safety and effectiveness in processes. Understanding this formula helps ensure that proper dilutions are made to achieve desired concentrations for different applications.
