Calculation path

Calculate ideal final volume and diluent addition for a ppm stock dilution. The page evaluates the displayed equation from your supplied values and presents both symbolic and substituted KaTeX working so the arithmetic can be checked.

C1V1=C2V2

What you provide

What you provide

  • Stock concentration expressed in ppm, using the same scenario as the other inputs
  • Stock aliquot volume expressed in mL, using the same scenario as the other inputs
  • Target concentration expressed in ppm, using the same scenario as the other inputs

What you receive

What you receive

  • Required final volume in mL from the stated equation
  • A symbolic formula plus substituted working with your values
  • Visible assumptions, field guidance, and an authoritative learning reference

Use boundary

Choose the maximum decimal places shown. This does not increase source accuracy.

Stock and target concentrations use the same ppm basis, volumes are additive, and no solute is lost.

Use internally consistent units and retain extra precision when carrying the result into another calculation.
