Stoichiometry and Ratios in Chemistry

These flashcards cover key vocabulary and concepts related to stoichiometry and the relationships between mass, moles, and chemical reactions.

Stoichiometry

The study of the relationship between the mass, the moles, and the molar mass of products and reactants within a chemical reaction.

Reactants

Substances that are required to fulfill a reaction.

Products

Substances that are produced as a result of a chemical reaction.

Mole to Mole

A type of stoichiometry that allows you to determine the mole of one substance based on the mole of another.

Mass to Mass

A type of stoichiometry that allows the calculation of the mass of one substance based on the mass of another.

Mass to Mole

A type of stoichiometry that involves determining the number of moles of one substance based on its mass.

Molar Mass

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

Mole Ratio

The ratio of coefficients in a balanced chemical equation, reflecting the proportion of reactants and products.

Avogadro's Number

A constant, approximately 6.022 x 10^23, that represents the number of particles in one mole of a substance.

Conversion Factor

A ratio used to convert from one unit to another, such as from liters of water to cans of juice in a recipe.

Chemical Equation

A mathematical representation of a chemical reaction using symbols to show the relationship between reactants and products.

C2H6O

The chemical formula for ethanol, where you can calculate the molar mass using the atomic masses of carbon, hydrogen, and oxygen.
