Stoichiometry and Molarity Review

These flashcards cover key vocabulary terms related to stoichiometry and molarity concepts important for the exam.

Stoichiometry

The area of chemistry that deals with the calculation of reactants and products in chemical reactions.

Molar Mass

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

Limiting Reactant

The reactant that is completely consumed in a chemical reaction, limiting the amount of product formed.

Percent Yield

The ratio of the actual yield of a product to the theoretical yield, expressed as a percentage.

Molarity

A measure of concentration; moles of solute per liter of solution.

Coefficients in a balanced equation

Numbers placed in front of compounds in a chemical equation to indicate the ratio of reactants to products.

Concentration

The amount of a substance per defined space; in molarity, it is expressed in moles per liter.

Redox Reaction

A chemical reaction involving the transfer of electrons between two species.

Conversion from grams to moles

To find the number of moles from grams, divide the mass in grams by the molar mass of the substance.

Actual Yield

The measured amount of a product obtained from a reaction.

Theoretical Yield

The maximum amount of a product that could be formed from a given amount of reactants.
