DATA ANALYSIS PACKAGE SYMBOL
converts molalities in an association where the keys are the component names (which can have a unit with unit prefix mmol/kg,μmol/kg,nmol/kg,pmol/kg) and values are the molalities to mass fractions with the specified unit quantifier (ppm, etc.), which is optional.
converts a molality of a component to a mass fraction assuming that it is the only solute.
- The molality is the molar amount of a substance per mass of the solvent.
- Components have to be defined using RegisterOxide or RegisterComp.
- Valid unit quantifiers are %, ppm, ppb, ppt, and ppq.
- Valid units for molalities are mol/kg, mmol/kg, μmol/kg, nmol/kg, and pmol/kg.
Calculate the mass fractions for a simple compound:
The calculated mass fraction is slightly different if a solute is not defined:
Use a unit quantifier for mass fractions:
Use a different unit for molalities:
