Recorded method
Reference fixtures, unit boundaries, invalid inputs, displayed formula, and limitations reviewed separately.
These records describe the published model and reference tests. A test-case count is not a certification of every possible input or an independent specialist review. Editorial policy
Known limitations
- The formula is intentionally scoped to the inputs shown and does not replace a validated laboratory method.
- Use consistent units and retain unrounded intermediate values.
- Confirm sample identity, purity, temperature, instrument behavior, and safety controls independently.
Reference inputs and expected results
Up to 12 examples from the configured definition fixtures are shown. Expected values use the stated output units; invalid inputs are intended to be rejected.
| Case | Inputs | Expected result |
|---|---|---|
| 1 M to 0.1 M, 100 mL | Stock concentration: 1 mol/L; Target concentration: 0.1 mol/L; Final volume: 100 mL | Stock volume to transfer: 10 mL; Approximate diluent volume: 90 mL; Dilution factor: 10 x (allowed numeric tolerance: 1.0E-6) |
| Reject target above stock | Stock concentration: 0.1 mol/L; Target concentration: 1 mol/L; Final volume: 100 mL | Reject invalid input: validation error |

Quick answer
This route applies C1V1 = C2V2 and reports both stock aliquot and approximate diluent volume. The final volume is the make-up volume, not solvent poured before the stock.
Formula and steps
Vstock = CtargetVfinal/Cstock; Vdiluent ≈ Vfinal − Vstock
Normalize the inputs first, keep working precision through intermediate steps, and round only the displayed result. Use the Dilution when the next step requires a different chemistry model.
Assumptions and limits
This is a transparent planning model with a defined scope. It does not validate an instrument, sample identity, chemical safety, purity, or a regulated procedure.
Frequently asked questions
What does this stock dilution recipe assume?
The assumptions shown above are part of the result. If your system falls outside them, select a more complete method rather than forcing the number.
How should I report the answer?
Keep the units, input basis, significant figures, and model limitations with the result.
