Full API documentation

Explanation

For Sodium Thiosulfate Pentahydrate, g/L is the base reference and molar mass is 248.18 g/mol. mmol/L -> g/L via the uses solute molar mass with si milli scaling. g/L -> % w/v via the definition: 1% w/v = 1 g per 100 ml = 10 g/l. Combined factor: 1 mmol/L = 0.024818 % w/v. Sodium Thiosulfate Pentahydrate keeps one fixed solution-concentration basis, so the snapshot, calculator, common values, and mirror route stay aligned.

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