Stoichiometry

These flashcards cover key definitions and concepts related to stoichiometry, chemical formulas, and calculations relevant to chemistry.

Molecular Formula

The formula that shows the number and type of different atoms in one molecule of a compound.

Empirical Formula

The simplest whole number ratio of different atoms in a molecule.

Binary Ionic Compound

A compound consisting of exactly two different elements, usually containing a metal cation and a non-metal anion.

Stoichiometry

The calculation of reactants and products in chemical reactions based on a balanced chemical equation.

Avogadro's Number

The number of particles in one mole of a substance, approximately $6.022 imes 10^{23}$.

Mole

The amount of substance containing Avogadro's number of particles.

Stoichiometric Coefficient

The numerical factor in front of a compound in a balanced chemical equation that indicates the ratio of moles.

Chemical Equation

A symbolic representation of a chemical reaction, showing the reactants and products.

Empirical Mass

The mass of the simplest whole number ratio of atoms in a compound.

Molar Mass

The mass of one mole of a substance, usually expressed in grams per mole.
