The manufacture of aluminum includes the production of cryolite (Na_AIF_ ) from the following reaction: $6 \mathrm{HF}(g)+3 \mathrm{NaAlO}_{2}(s) \rightarrow \mathrm{Na}_{3} \mathrm{AlF}_{6}(s)+3 \mathrm{H}_{2} \mathrm{O}(\ell)+\mathrm{Al}_{2} \mathrm{O}_{3}(s)$. How much NaAlO, (sodium aluminate) is required to produce $1.00 \mathrm{kg}$ of $\mathrm{Na}_{3} \mathrm{AlF}_{6} ?$

Key Concepts

Mole Concept

The mole concept provides a bridge between the atomic scale and measurable quantities in the laboratory by defining a mole as the amount of substance containing Avogadro's number of particles (approximately 6.022×10^23). This allows chemists to count atoms and molecules by weighing a substance.

Stoichiometry

Stoichiometry involves using a balanced chemical equation to determine the quantitative relationships among reactants and products in a chemical reaction. This concept is critical for calculating how much of one substance is needed to produce a given amount of another by using the mole ratios indicated in the equation.

Molar Mass

Molar mass is the mass of one mole of a substance, measured in grams per mole. It is calculated by summing the atomic masses of all the atoms in a molecule, and it serves as a key conversion factor between moles and mass in stoichiometric calculations.

Balanced Chemical Reactions

Balanced chemical reactions are equations in which the number of atoms of each element is equal on both the reactant and product sides, reflecting the law of conservation of mass. They provide the necessary stoichiometric coefficients that guide quantitative calculations in chemical processes.
