Solutions & Concentration
Prepare and characterize solutions using concentration and dilution relationships.
Calculators
Molarity CalculatorCalculate molarity, solute amount, or solution volume from the known values.Molar Dilution CalculatorCalculate a molar dilution with M1V1 = M2V2. Find the stock volume, final molarity, or diluent to add in M, mM, or µM.Concentration CalculatorCalculate molarity, mass concentration, percent concentration, ppm, or ppb.Serial Dilution CalculatorCreate a stage-by-stage serial dilution plan with transfer and diluent volumes.Molarity and MolalityCalculate molarity and molality for the same solution. Compare mol/L and mol/kg, and convert between them with the solution density.Normality CalculatorCalculate reaction-specific normality from molarity, equivalents, or equivalent weight.PPM CalculatorCalculate ppm by mass, volume, moles, density, percent, or ppb.
