Key Concepts

Molar Mass

Molar mass is the mass in grams of one mole of a substance, and it is used to convert between the mass of a substance and the number of moles. This conversion is essential when calculations require the use of moles, as provided by the stoichiometric coefficients in the reaction.

Limiting Reactant

The limiting reactant is the substance that is entirely consumed first, thereby limiting the amount of product formed. Identifying the limiting reactant is crucial in predicting the maximum yield of a reaction, especially when reactant amounts are not in the exact stoichiometric ratio.

Mole Ratio

The mole ratio, derived from the coefficients of the balanced chemical equation, indicates the proportional relationship between reactants and products. It is used to convert between moles of one substance and moles of another involved in the reaction.

Stoichiometry

Stoichiometry involves using the quantitative relationships established by a balanced chemical equation to calculate the amounts of reactants and products. It is central to relating the mole ratios of substances consumed and produced in a reaction.
