Full API documentation

Explanation

For Sodium Sulfate, g/L is the base reference and molar mass is 142.04 g/mol. ppm -> g/L via the dilute aqueous approximation: 1 ppm ~= 1 mg/l. g/L -> mmol/L via the uses solute molar mass with si milli scaling. Combined factor: 1 ppm = 0.00704027034638 mmol/L. Sodium Sulfate keeps one fixed solution-concentration basis, so the snapshot, calculator, common values, and mirror route stay aligned.

Neutral sulfate salt reference. When molar units are involved, the same molar-mass assumption stays constant rather than switching reference values between blocks.

Method & Solute Basis

Method basis: this conversion runs through grams per liter and uses the molar mass of Sodium Sulfate whenever a molar unit is involved.
Solute reference: Sodium Sulfate. The page keeps one fixed g/L normalization path for this solute.
Consistency rule: calculator output and table values use the same constants and rounding policy.
Source: Solution concentration reference model (Fixed molar masses (g/mol), SI concentration definitions, and dilute aqueous approximations where ppm ≈ mg/L and ppb ≈ ug/L.)
