Calculate stock molarity from declared mass, molar mass and solution volume, then review dilution volumes with both complete original reports.

Limitations

Choose or paste UTF-8 JSON with exactly massGrams, molarMassGramsPerMole and stockVolumeLitres as quoted numeric strings: grams, g/mol and final stock-solution litres. Each value is single-line, up to 128 characters; source limit 4 KiB and 1,024 UTF-16 units. Raw source/BOM/spacing are retained; duplicate, extra or nonstring fields refuse. Calculated stock mol/L feeds target mol/L and final mL. Required volumes do not check remaining stock. Declared-solute/additive-volume/no-reaction arithmetic only; no purity, hydrate, temperature, contraction or compatibility model. Zero/unsupported stock keeps its molarity checkpoint and refuses downstream; valid zero target retains null dilution factor. The ZIP keeps source, exact arguments and both complete reports, unredacted. Limits: 30 seconds per calculation, 90 seconds overall.
Original mass0..1e12g,declaredMMg/mol and stocksolutionL positive1e-12..1e12. Seven molarity fields retained. Exact original order mass/MM then moles/V,not algebraic reassociation. Actual M to String(number),no basis conversion or stock concentration override. Original target0..stock/finalmL bounds and all seven dilution fields unchanged,including nullfactor zero-target and IEEE underflow/nonfinite-output rules.
