Enter the molarity and volume into the calculator to determine the number of moles. This calculator can also evaluate any of the variables given the others are known.

Molarity To Moles Formula

The following formula is used to calculate the number of moles from molarity.

Moles = M * V

Variables:

  • Moles is the number of moles of the solute
  • M is the molarity of the solution (moles/L)
  • V is the volume of the solution (L)

To calculate the number of moles, multiply the molarity of the solution by the volume of the solution. This will give you the number of moles of the solute in the solution.

What is Molarity To Moles?

Molarity to moles is a conversion process used in chemistry to determine the number of moles of a solute in a solution. Molarity is a measure of the concentration of a solute in a solution, expressed as the number of moles of solute per liter of solution. By multiplying the molarity by the volume of the solution in liters, you can calculate the number of moles of the solute. This conversion is useful in various chemical calculations, such as stoichiometry and dilution problems.

How to Calculate Molarity To Moles?

The following steps outline how to calculate the number of moles (Moles) using the formula Moles = M * V.


  1. First, determine the molarity of the solution (M) in moles per liter (moles/L).
  2. Next, determine the volume of the solution (V) in liters (L).
  3. Next, gather the formula from above: Moles = M * V.
  4. Finally, calculate the number of moles (Moles) using the formula.
  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.

Molarity of the solution (M) = 0.5 moles/L

Volume of the solution (V) = 2 liters
