Model and interpretation
C₁V₁ = C₂V₂ assumes consistent concentration units, ideal additive volumes and no reaction. The target cannot exceed the stock concentration. Volumes are in mL. This is not dosing, chemical-handling or mixing-safety guidance. 10⁻¹² ≤ C₁,V₂ ≤ 10¹²; 0 ≤ C₂ ≤ C₁.

What this calculator answers
Dilution Calculator applies the registered method “C₁V₁ = C₂V₂; V₁ = C₂V₂/C₁; Vd = V₂−V₁” to the displayed Stock concentration (C₁), Target concentration (C₂), Final volume (mL) inputs. Both worked examples come from the production calculation engine, and OpenStax Chemistry 2e — Molarity and dilution defines the cited method or convention; no hidden inputs or current external data are inferred.
Variables, defaults, and limits
- Stock concentration (C₁)
- Stock concentration (C₁) is a number input. The displayed starter value is 10; it is an example, not a hidden assumption.
- Default: 10
- Accepted values: Allowed range: 0.000000000001 to 1,000,000,000,000. Numeric entries must be finite and unambiguous.
- Target concentration (C₂)
- Target concentration (C₂) is a number input. The displayed starter value is 2; it is an example, not a hidden assumption.
- Default: 2
- Accepted values: Allowed range: 0 to 1,000,000,000,000. Numeric entries must be finite and unambiguous.
- Final volume (mL)
- Final volume (mL) is a number input. The displayed starter value is 100; it is an example, not a hidden assumption.
- Default: 100
- Accepted values: Allowed range: 0.000000000001 to 1,000,000,000,000. Numeric entries must be finite and unambiguous.
Formula and calculation rule
R[dilution-calculator]=C₁V₁ = C₂V₂; V₁ = C₂V₂/C₁; Vd = V₂−V₁; x₁=Stock concentration (C₁); x₂=Target concentration (C₂); x₃=Final volume (mL)Dilution Calculator evaluates the registered expression “R[dilution-calculator]=C₁V₁ = C₂V₂; V₁ = C₂V₂/C₁; Vd = V₂−V₁; x₁=Stock concentration (C₁); x₂=Target concentration (C₂); x₃=Final volume (mL)” with the validated inputs. Full calculation precision is retained until the result is formatted for display.
Worked examples
Dilution Calculator evaluated example 2
Change one valid input or choice and evaluate Dilution Calculator again to check that the result responds deterministically.
Inputs- Stock concentration (C₁): 2
- Target concentration (C₂): 0.5
- Final volume (mL): 100
Evaluated result: 25 mL
Assumptions
- Dilution Calculator uses the visitor-entered values exactly as labelled; it does not retrieve private records or current rates.
- The calculation is limited to the declared relationship: R[dilution-calculator]=C₁V₁ = C₂V₂; V₁ = C₂V₂/C₁; Vd = V₂−V₁; x₁=Stock concentration (C₁); x₂=Target concentration (C₂); x₃=Final volume (mL).
- Intermediate values are not rounded; display rounding is applied only at the presentation boundary.
- The deterministic calculation runs locally and does not upload calculator inputs to the application API.
- The model assumes the displayed units and idealized relationship; it is not a substitute for safety-critical design or professional measurement.
Validation and boundaries
- Every visible required input must be present; a missing value is never replaced with zero.
- NaN, positive or negative infinity, unsafe overflow, and a non-finite final result are rejected.
- Field-specific minimums, maximums, and choices apply to Stock concentration (C₁), Target concentration (C₂), Final volume (mL).
- Unit consistency and the displayed idealized model are required; unsafe or physically unsupported values are rejected.
Review and correction links
Common mistakes
- Confirm the meaning and unit of Stock concentration (C₁), Target concentration (C₂), Final volume (mL) before calculating; a numerically valid value can still use the wrong convention.
- Do not round intermediate values when checking the result, because early rounding can change the last displayed digits.
- Changing an unstated real-world assumption does not change the calculator until the corresponding displayed input is changed.
- Do not apply the idealized result to safety-critical hardware or structures without qualified review and measured tolerances.
Frequently asked questions
- What question does Dilution Calculator answer?
- Find stock and diluent volumes for an ideal dilution using consistent concentration units and a final volume in mL. The implemented relationship is R[dilution-calculator]=C₁V₁ = C₂V₂; V₁ = C₂V₂/C₁; Vd = V₂−V₁; x₁=Stock concentration (C₁); x₂=Target concentration (C₂); x₃=Final volume (mL).
- Which inputs does Dilution Calculator use?
- It uses the visible fields Stock concentration (C₁), Target concentration (C₂), Final volume (mL). No hidden value is substituted for an omitted required input.
- What happens when Dilution Calculator receives an invalid or extreme value?
- The page rejects missing, ambiguous, out-of-range, or non-finite values and refuses to display a non-finite result.
- Why can Dilution Calculator differ from another result?
- Different unit conventions, endpoint policies, fee or rate assumptions, formula domains, and premature rounding can produce a different answer.
- Can I use Dilution Calculator as professional advice?
- No. It is an educational model and is not certified engineering or safety analysis.
- How can I verify the Dilution Calculator result?
- Recalculate the two evaluated examples without rounding intermediate values and compare the declared formula or convention with OpenStax Chemistry 2e — Molarity and dilution.
