Enter the amount of solute and volume of the solution into the calculator to determine the ionic concentration. This calculator can also evaluate any of the variables given the others are known.

Ionic Concentration Formula

The following formula is used to calculate the ionic concentration in a solution.

C = n / V


  • C is the ionic concentration (mol/L) n is the amount of solute (mol) V is the volume of the solution (L)

To calculate the ionic concentration, divide the amount of solute by the volume of the solution. The result will be the ionic concentration in moles per liter (mol/L).

What is an Ionic Concentration?

Ionic concentration refers to the amount of ions in a particular volume of a solution. Ions are atoms or molecules that have lost or gained electrons, resulting in a positive or negative charge. The concentration is usually measured in moles per liter, a unit that represents the number of ions in a liter of solution. This measurement is crucial in various fields such as chemistry, biology, and environmental science, as it can influence chemical reactions, biological processes, and the health of ecosystems.

How to Calculate Ionic Concentration?

The following steps outline how to calculate the Ionic Concentration using the formula C = n / V.

  1. First, determine the amount of solute (n) in moles.
  2. Next, determine the volume of the solution (V) in liters.
  3. Next, gather the formula from above = C = n / V.
  4. Finally, calculate the Ionic Concentration (C) in mol/L.
  5. After inserting the values of n and V into the formula 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.

amount of solute (n) = 0.5 mol

volume of the solution (V) = 0.2 L
