Enter the total moles of solute and the total liters of solution into the calculator to determine the molar concentration of the solution.

Molar Concentration Formula

The following is the molar concentration formula: 

M = n / v
  • Where M is the molar concentration (moles/L)
  • n is the total number of moles of solute
  • v is the total volume of the solution

To calculate the molar concentration, divide the number of moles of solute by the volume of the solution.

Molar Concentration Definition

A molar concentration is defined as a ratio of the total moles of a solute to the total moles of a solution. This is also often referred to as molarity.

Are molar concentration and molarity the same thing?

Molar concentration and molarity are synonymous. They are both ways of describing the total number of moles of a solute in a certain volume of a solution.

What is 1 molar concentration?

A 1 molar concentration means that there is a total of 1 mole of a substance in 1 liter of a volume.

Can molar concentration be negative?

The molar concentration of any mixture cannot be negative. If looking in terms of the change in molar concentration, then yes, the change in the concentration could be negative.

Is a molar concentration the same as molar mass?

A molar mass is not the same as a molar concentration. A molar mass is a measure of the number of moles per unit of mass, while a concentration is the number of moles per unit of volume.

Does molar concentration depend on temperature?

A molar concentration only depends on the moles and volume, however, if the volume of the solution changes because of a change in temperature, such as water boiling off, then the molar concentration will change.

Why is molar concentration useful?

Molar concentration is most used when analyzing chemical solutions and processes. The analysis of these solutions and changes in moles is the basis of many useful processes.

How to calculate molar concentration?

  1. First, determine the number of moles of the substance in the questions.
  2. Next, determine the total volume of the solution or area the substance is contained within.
  3. Finally, calculate the molar concentration by dividing the number of moles by total volume.
