How to use Ideal Gas Mixture Composition Workbench

Convert each declared component using its supplied g/mol molar mass, then normalize moles and grams separately. Dalton’s ideal-mixture model scales total pressure by mole fraction; total moles use PV=nRT at the common Kelvin temperature.

  1. Enter model json (schema and units below).
  2. Choose the stated convention and check the units and supported model.
  3. Calculate, inspect the result, then copy or download it.

Good to know

  • Plain decimal JSON numbers or strings, at most six fractional places, magnitude at most 1,000,000,000; raw numeric spellings and duplicate object members are checked. Exact rational arithmetic is capped at 8,192 bits. Text is at most 30,000 characters; a local JSON download preserves exact fractions or full stored approximate numbers. 1–30 components, nonnegative amounts, positive total and molar masses 0.000001–1,000,000 g/mol. Temperature 0.000001–1,000,000 K and pressure 0.000001–1,000,000,000 Pa. Ideal nonreacting gases only; no compressibility, phase, fugacity, composition inference, cylinder safety or experiment instructions. R=8.31446261815324 J/(mol K).
  • Local calculation only; no input persistence or external lookup. Text/JSON is limited to 30000 characters and output to 1000000 characters. Numeric model inputs and precision/work limits are stated on this page. Approximate JSON numbers retain full stored values; exact arithmetic outputs retain decimal or fraction strings. Unsupported states fail explicitly.

Common questions

Are mole and mass percentages interchangeable?

No. Different molar masses give different mass shares for the same mole shares. Both fractions remain visible in the report.

Is the input uploaded or saved?

No. The tool calculates inside this browser tab and provides a local download; it does not persist your input.
