  • Law of Definite Proportions
    A principle stating that a pure compound always contains the same elements in the same mass ratio, regardless of sample origin.
  • Proust's Law
    An alternative name for the rule that chemical compounds have constant elemental mass proportions, named after its originator.
  • Law of Constant Composition
    A synonym for the concept that the elemental makeup by mass in a compound is unchanging across all samples.
  • Mass Ratio
    A numerical value found by dividing the mass of one element in a compound by the mass of another, indicating their relative amounts.
  • Chemical Compound
    A pure substance formed from two or more elements combined in fixed mass proportions.
  • Constituent Element
    A basic substance that makes up a compound, contributing a specific mass to the whole.
  • Atomic Mass
    A value representing the mass of a single atom, typically measured in grams per mole, used to calculate compound composition.
  • CO2
    A molecule consisting of one carbon atom and two oxygen atoms, used as an example to illustrate fixed mass ratios.
  • Sample Origin
    The geographic or physical source from which a compound is obtained, shown to not affect mass proportions.
  • Verification pipeline
    A process involving comparison of mass ratios from different samples to confirm compound identity.
  • Periodic Table
    A chart listing elements and their atomic masses, essential for calculating the mass contributions in compounds.
  • Pure Substance
    A material with a uniform and definite composition, such as a compound with unchanging mass ratios.
