Enter the final volume, desired concentration, and stock concentration into the calculator below to determine the total volume of stock concentration needed to dilute your substance to your desired amount.

Dilution Formula

This calculator used the following formula to calculate the volume that needs to be added. 

M1V1 = M2V2

M1V1 = M2V2

  • Where M1 is the initial molarity
  • V1 is the initial volume
  • M2 is the final molarity
  • V2 is the final volume

Dilution Definition

Dilution is a concept used to describe the reduction of concentration or strength of a substance. It occurs when a solute, typically a solid or liquid, is added to a solvent to create a solution with a lower concentration. This process involves increasing the volume of the solvent while keeping the amount of solute constant.

Dilution is vital in various fields and applications due to its ability to adjust concentrations, which has numerous practical implications. In chemistry, dilution plays a crucial role in laboratory experiments and manufacturing processes.

By diluting a solution, scientists can create different concentrations of a substance, allowing them to study its properties, reactivity, or toxicity at varying strengths. This is particularly important when testing the effects of chemicals, drugs, or pollutants on living organisms or the environment.

How to calculate dilution?

How to calculate a dilution

  1. FIrst, determine the initial molarity and initial volume.

    This is the initial molarity and volume of the solution at time = 0.

  2. Next, determine the final volume

    This will be the final Volume of the solution after a certain time where another solution or base has been added to the solution.

  3. Calculate the final molarity

    Molarity and Volume are directly proportional. With 3 variables the 4th can be calculated.
