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
