  • Molecular Formula
    Shows the actual count of each type of atom present in a single molecule of a compound.
  • Empirical Formula
    Represents the simplest whole-number ratio of elements in a compound, not the actual atom count.
  • Subscript
    A small number written after an element symbol indicating the quantity of that atom in a formula.
  • N Factor
    A multiplier applied to the empirical formula's subscripts to obtain the molecular formula.
  • Glucose
    A compound with a molecular formula derived by multiplying its empirical formula by 6.
  • Octane
    A compound whose molecular formula results from doubling the subscripts of its empirical formula.
  • Salicylic Acid
    A compound where the empirical and molecular formulas are identical due to an n factor of 1.
  • Element
    A pure substance consisting of only one type of atom, represented in chemical formulas.
  • Compound
    A substance formed from two or more elements chemically combined in fixed proportions.
  • Mass Percentage
    The proportion by mass of each element present in a compound, used to determine formulas.
  • Ratio
    A comparison of the quantities of elements, foundational for empirical formula determination.
  • Subscript Multiplication
    The process of scaling empirical formula subscripts by the n factor to yield the molecular formula.
