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.

• Molarity is calculated by dividing the number of moles of solute by the volume of the solution in liters.

• It is commonly denoted by the symbol 'M'.

• For example, a solution containing 0.5 moles of solute in 1 liter of solution has a molarity of 0.5 M.
