Molarity is a concentration unit of a solution expressed as moles of solute dissolved per liter of solution. In short, the molarity describes how many moles of solute are in each liter of solution. M or Molar are the abbreviations for Molarity.

To do a Molarity problem, all that is needed is this simple equation: Molarity (M) = # moles of Solute / # liters of Solution. This equation can also be used to find the # moles of solute or the # liters of solution depending on the information given. Click on the link below to see a few example problems.

Molarity(M) = # moles of Solute / # liters of Solution
