Molecular Weight Calculator

Enter the chemical formula of a compound to calculate its molar mass and elemental composition:

  • Calculate

    • Total Molecular Weight:

    • g/mol

    Tip: Chemical formula is case sensitive. C10H16N2O2 c10h16n2o2

    Dilution Calculator

    Calculate the dilution required to prepare a stock solution. The Selleck dilution calculator is based on the following equation:

    Concentration (start) × Volume (start) = Concentration (final) × Volume (final)

    This equation is commonly abbreviated as: C1V1 = C2V2 (Input Output)

    • C1

      V1

      C2

      V2
