About Molarity

Molarity (M) is a measure of the concentration of a solute in a solution, expressed as the number of moles of solute per liter of solution.

Formula:

Molarity = Moles of Solute ÷ Volume of Solution (in liters)

Where:

  • Moles of Solute = Mass of Solute ÷ Molecular Weight
  • Volume of Solution = Total volume of the solution in liters
  • Molarity = Concentration in moles per liter (mol/L)

Applications:

  • Preparing standard solutions for laboratory work
  • Dilution calculations
  • Stoichiometry problems
  • Chemical reaction calculations
  • Quality control in chemical manufacturing
