About Concentration Units
Concentration units express the amount of solute in a given amount of solution or solvent. Calculations cover molarity, molality, normality, mole fraction, mass percentage, volume percentage, parts per million and dilution, including the effect of temperature on volume-based units and the distinction between molarity and molality.
