Nitrogen reacts with hydrogen to produce ammonia. $$ \mathrm{N}_{2}(g)+3 \mathrm{H}_{2}(g) \longrightarrow 2 \mathrm{NH}_{3}(g) $$ a. If you have $3.64 \mathrm{~g}$ of $\mathrm{H}_{2}$, how many grams of $\mathrm{NH}_{3}$ can be produced? b. How many grams of $\mathrm{H}_{2}$ are needed to react with $2.80 \mathrm{~g}$ of $\mathrm{N}_{2}$ ? c. How many grams of $\mathrm{NH}_{3}$ can be produced from $12.0 \mathrm{~g}$ of $\mathrm{H}_{2}$ ?

Key Concepts

Mole Concept

The mole is a fundamental unit in chemistry that represents a specific number of particles, usually atoms or molecules. The mole concept bridges the gap between the atomic scale and macroscopic measurements, enabling conversion between mass and number of particles via Avogadro's number.

Stoichiometry

Stoichiometry involves the quantitative relationship between reactants and products in a chemical reaction. It uses the molar ratios derived from balanced chemical equations to calculate the amounts of substances consumed and produced during the reaction.

Balanced Chemical Equations

Balanced chemical equations show the reactants and products in a chemical reaction with stoichiometric coefficients that ensure the conservation of atoms. They serve as the roadmap for stoichiometric calculations by indicating the ratio in which substances react and are produced.

Molar Mass

Molar mass is the mass of one mole of a substance, expressed in grams per mole (g/mol). It is used as a conversion factor to translate between the mass of a substance and the number of moles, which is vital in quantitative chemical calculations.
