Enter the volume in milliliters and the molarity of the solution into the calculator to convert the volume to millimoles.

ml to mmol Formula

The formula to convert milliliters to millimoles is:

mmol = Volume (ml) * Molarity (M)

Variables:

  • mmol is the number of millimoles
  • Volume is the volume of the solution in milliliters (ml)
  • Molarity (M) is the concentration of the solution in moles per liter (mol/L)

To calculate the number of millimoles, multiply the volume of the solution in milliliters by the molarity of the solution.

What is Molarity?

Molarity is a measure of the concentration of a solute in a solution, or of any chemical species, in terms of amount of substance in a given volume. It is commonly expressed in moles per liter (mol/L). Molarity is used in chemistry to express the concentration of chemical substances. To calculate molarity, one divides the number of moles of solute by the volume of the solution in liters.

How to Calculate ml to mmol?

The following steps outline how to calculate millimoles from milliliters and molarity.


  1. First, determine the volume of the solution in milliliters (ml).
  2. Next, determine the molarity of the solution (M).
  3. Use the formula mmol = Volume (ml) * Molarity (M).
  4. Finally, calculate the number of millimoles (mmol).
  5. After inserting the variables and calculating the result, check your answer with the calculator above.

Example Problem :

Use the following variables as an example problem to test your knowledge.

Volume of the solution (ml) = 50 ml

Molarity of the solution (M) = 0.2 M
