Lecture 10: Determining Empirical and Molecular Formulas

This set of flashcards covers key terms and concepts related to determining empirical and molecular formulas, including relevant examples.

Empirical Formula

The simplest whole-number ratio of atoms of each element in a compound.

Molecular Formula

A formula that shows the actual number of atoms of each element in a molecule of the compound.

Adipic Acid

A compound with the formula C6H10O4, commonly used in the production of nylon.

Learning Check

Exercises used to assess understanding of material; in this case, to determine empirical and molecular formulas.

Caffeine

A stimulant found in coffee and tea, with the molecular formula C8H10N4O2.

Percent Composition

The percent by mass of each element in a compound, used to determine empirical formulas.

Molar Mass
