Mass and Mole Relationships Continued: Molar Ratios

These flashcards cover the key concepts related to molecular weight, molar mass, mole ratios, and the process of converting between quantities in chemistry.

Molecular weight

The weight of a molecule calculated from the atomic weights of its constituent atoms.

Molar mass

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

Mole ratio

The ratio of the number of moles of one substance to the number of moles of another substance in a balanced chemical equation.

Mass-to-mass conversion

A process that requires the use of both molar mass and mole ratios to convert between the masses of different substances.

Reactants

Substances that undergo a chemical change in a reaction.

Products

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

Coefficient

A number in front of a reactant or product in a chemical equation that tells how many moles or molecules are involved.

Conversion factor

A ratio used to express how many of one unit is equal to another unit.
