CEM 141 – Stoichiometry

A set of vocabulary flashcards covering key concepts from the lecture on stoichiometry.

Stoichiometry

The relationship between the macroscopic and molecular level in chemistry.

Mole

A counting unit in chemistry equivalent to $6.022 imes 10^{23}$ 'things'.

Avogadro's number

The number of things in one mole, which is $6.022 imes 10^{23}$.

Molar mass

The mass of one mole of a substance in grams, equal to its formula mass.

Limiting reactant

The reactant that limits the amount of product that can be formed in a chemical reaction.

Reaction stoichiometry

The calculation involving the amounts of reactants and products in a chemical reaction.

Percent yield

The ratio of the actual amount produced to the theoretical amount, multiplied by 100.

Balanced equation

An equation with equal numbers of each type of atom on both sides, indicating conservation of mass.
