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.
