Stoichiometry and Molarity Concepts

These flashcards cover key vocabulary related to stoichiometry, yield calculations, and solutions.

Stoichiometry

A predictive tool used to calculate the quantities of reactants and products in a chemical reaction, based on the balanced chemical equation.

Theoretical Yield

The maximum amount of product that could be formed from the given amounts of reactants, assuming perfect reaction conditions.

Actual Yield

The actual amount of product obtained from a chemical reaction, measured after the reaction has occurred.

Percent Yield

A measure of the efficiency of a reaction, calculated by dividing the actual yield by the theoretical yield and multiplying by 100.

Molar Mass

The mass of one mole of a substance, calculated by adding the atomic masses of the elements in its chemical formula.

Molarity (M)

A way to express concentration, defined as the number of moles of solute per liter of solution.

Dilute Solution

A solution that contains a relatively low concentration of solute.

Coefficients (in stoichiometry)

Numbers in a balanced chemical equation that describe the ratio of moles of each substance involved in the reaction.
