Precision tools for solution preparation, concentration conversion, and serial dilution design.
Calculate Mass from Volume & Concentration
Enter the desired concentration, formula weight, and target volume to find the exact mass of solute needed.
Mass (g) = Concentration (M) × Volume (L) × Formula Weight (g/mol)Calculate Molarity from Mass & Volume
Determine the molar concentration of a solution given the dissolved mass, molecular formula weight, and final volume.
Molarity (M) = Mass (g) ÷ [Formula Weight (g/mol) × Volume (L)]Serial Dilution Calculator
Design a step-wise dilution series. Set your starting concentration, dilution factor, and steps to generate a complete protocol table.
Use the formula: Mass (g) = Molarity (M) x Volume (L) x Formula Weight (g/mol). Our Molarity Calculator performs this calculation automatically — enter your desired concentration, volume, and select the chemical from our 70+ compound database.
Molarity (M) = Mass (g) / (Formula Weight (g/mol) x Volume (L)). Switch to the Molarity tab in our calculator, enter the mass of solute, formula weight, and solution volume to get the molar concentration.
A serial dilution is a stepwise dilution of a substance in solution, where each step uses the same dilution factor. Our Serial Dilution Calculator generates the complete dilution protocol with volumes and concentrations for each step.
