`"Amount of Substance"_"(converted)" = `

The Amount of Substance Conversion equation converts a measurement of the amount of a substance from one of vCalc's standard units to another unit. You enter a numeric value for the input amount of substance and choose a unit for the input value. Then you select an output unit with the resultant value.


Units between which you can perform conversions are:

mole (mol) - a unit of measurement used in chemistry to express amounts of a chemical substance.  The mole is defined to be the amount of substance that contains as many elementary entities (e.g., atoms, molecules, ions, electrons) as there are atoms in 12 grams of pure carbon-12 (12C).1 The number of elementary particles in pure 12C is the same as Avagadro's number (NA): 6.02214129(27)×1023 mol?1. See Avagadro's Number in vCalc's constants.

atom - a unit expressing the number of atoms.  This unit is related to the mole, where one mole of substance will contain Avagadro's number (NA) of atoms by definition.

osmole - the osmole (Osm or osmol) is a non-SI unit of measurement that defines the number of moles of solute that contribute to the osmotic pressure of a solution.2
