About Concentration Calculations

Formula

C = (mass / MW) / volume

Common Units

  • Molarity (M): moles per liter of solution
  • Molality (m): moles per kilogram of solvent
  • Normality (N): equivalents per liter of solution
  • Weight/Volume %: grams of solute per 100 mL of solution
  • Parts per Million (ppm): mass ratio × 10⁶

How to Use

  1. Select the desired concentration unit
  2. Enter the mass of solute
  3. Enter the molecular weight
  4. Enter the volume of solution
  5. Enter density if required for your unit
  6. Click Calculate to get the concentration

Applications

  • Preparing standard solutions
  • Laboratory experiments
  • Chemical analysis
  • Quality control
  • Research and development

Important Notes

  • Ensure all units are consistent
  • Density is required for molality and percentage calculations
  • Molecular weight should be in g/mol
  • Volume units will be converted automatically
