Moles: Unit 3

Flashcards covering key vocabulary and concepts related to moles and stoichiometry from Chapter 5.

Stoichiometry

The relationship between reactants and products in a chemical reaction; helps predict quantities.

Avogadro’s number

6.022 x 10^23; the number of molecules or atoms in one mole of a substance.

Limiting reactant

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

Theoretical yield

The maximum amount of product that can be produced from a given amount of reactants based on stoichiometry.

Actual yield

The amount of product obtained from a chemical reaction, which may differ from the theoretical yield.

Percent yield

A measure of the efficiency of a reaction, calculated as (Actual Yield / Theoretical Yield) x 100.

Mole

A unit of measurement in chemistry representing 6.022 x 10^23 entities (atoms, molecules, etc.).

Molar mass

The mass of one mole of a substance, typically expressed in grams per mole (g/mol).

Mole to mass conversion

The process of converting moles of a substance to grams using its molar mass.

Atom economy

A measure of the efficiency of a reaction in terms of the mass of products obtained from the mass of reactants.
