x402
Chemistry Calculators – Dilution Calculator (C1V1=C2V2) is a paid API for AI agents from chemistry-calc.x402tookit.com, paid per call via x402, $0.02/call, status unknown (last checked 2026-10-30).
Solves the dilution equation C1×V1=C2×V2 for any missing variable given three known values, and returns solvent to add and dilution factor.

How this service works
Dilution equation C1 x V1 = C2 x V2: give any three values and get the fourth, plus solvent to add and the dilution factor.
Output
Returns the four dilution variables (C1, C2, V1, V2) with the unknown solved, plus the volume of solvent to add, the dilution factor (C1/C2), and the stock fraction. Also includes a summary string and any applicable disclaimer or degraded-mode flags.
Example use cases
Lab solution preparation from stock
“I have a 100 mM stock solution and I want to prepare 50 mL of a 5 mM working solution. How much stock should I pipette and how much buffer do I add?”
Back-calculate stock concentration
“I took 2 mL of my stock and diluted it to a final volume of 40 mL, and the final concentration came out at 0.25 mg/mL. What was the original stock concentration?”
Find final volume for target concentration
“I have 10 mL of a 2 M NaCl solution and I want to dilute it to 0.1 M. What final volume do I need and what's the dilution factor?”

Endpoint
GEThttps://chemistry-calc.x402tookit.com/dilution?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a precise, programmatic solution to the standard dilution equation (C1V1=C2V2), especially inside an automated lab workflow or agent pipeline. It is purpose-built for chemistry dilution math and returns structured numeric results (including solvent to add and dilution factor) rather than a free-text explanation, making it preferable over a general LLM calculation for reproducibility and downstream data use.
Side effects
- Fewer than three of the four parameters provided — endpoint cannot solve for more than one unknown
- Physically impossible values (e.g. final concentration greater than stock concentration) may return an error or null result
- Mismatched units (mixing mL and L, or mM and M) cause incorrect results since no unit conversion is performed
- Missing required query parameters returns a 400 or null response
