  • Weight Percent
    A synonym for the percentage of a particular element’s mass relative to the total mass of a compound.
  • Percent Composition
    A breakdown showing the proportion by mass of each element present in a compound.
  • Molar Mass
    The mass in grams of one mole of a substance, crucial for calculating element proportions in compounds.
  • Element
    A pure substance consisting of only one type of atom, whose mass contribution is analyzed in compounds.
  • Compound

  • Mole
    A standard quantity representing Avogadro’s number of particles, used to relate mass and number of entities.
  • Formula
    A mathematical expression used to calculate the percentage of an element’s mass in a compound.
  • Selected Element
    The specific atom within a compound whose mass contribution is being determined as a percentage.
  • Total Mass
    The combined mass of all elements in a compound, serving as the denominator in percent calculations.
  • Numerator
    The mass of the chosen element in a compound, placed above the division line in the percent formula.
