The 14 pages that link to Amount of substance, each with the reason it gives.

• Ideal gas lawRelated: The variable n counts gas in moles, rather than tracking each molecule individually.

• ConcentrationRelated: Concentration can count particles through the mole rather than weigh them directly.

• Avogadro constantNarrower topic: The constant connects this quantity to a count of entities.

• Ideal gasRelated: The ideal gas law uses moles to represent the number of gas particles.

• Mole fractionNarrower topic: The numerator and denominator are amounts of substance, not masses or volumes.

• Dalton's law of partial pressuresRelated: Component mole amounts determine their mole fractions and partial pressures.

• MoleNarrower topic: The mole is the SI base unit used to express this quantity.

• Avogadro's lawNarrower topic: It is the measurable quantity that represents particle count in the proportionality.

• Molar volumeRelated: Molar volume is defined by dividing volume by amount of substance.

• MolalityNarrower topic: Molality counts solute in moles, the SI unit for amount of substance.

• Gas pressureRelated: Adding gas particles increases pressure when volume and temperature remain fixed.

• Charles's lawRelated: The amount of gas must stay fixed; otherwise volume also changes with particle count.

• Intensive and extensive propertiesRelated: Extensive properties typically scale with the amount of substance.

• Combined gas lawRelated: The gas sample's amount must remain fixed for the combined gas law to hold.
