Enter the initial molarity, initial volume, and final volume into the calculator to determine the final molarity from dilution.

Molarity Dilution Formula

The following formula can be used to calculate the final molarity of a diluted substance. 

M2 = M1*V1/V2
  • Where M2 is the final molarity (moles/L)
  • M1 is the initial molarity (moles/L)
  • V1 is the initial volume (L)
  • V2 is the final volume (L)

To calculate a final molarity through dilution, multiply the initial molarity by the initial volume, then divide by the final volume.

Molarity Dilution Definition

Molarity dilution is the process of decreasing the number of moles of a substance per volume of a solution through the process of dilution.

What is dilution?

Dilution is the decreasing of a concentration of a substance through adding a base or another substance.

Molarity Dilution Example

How to calculate a molarity dilution?

  1. First, determine the initial molarity.

    Measure or calculate the initial molarity.

  2. Next, determine the initial volume.

    Measure the initial volume of the solution.

  3. Next, determine the final volume.

    Measure the final volume of solution after dilution has occurred.

  4. Finally, calculate the molarity.

    Calculate the final molarity using the equation above.
