This reaction between lithium hydroxide and carbon dioxide has been used to remove $\mathrm{CO}_{2}$ from spacecraft atmospheres: $$ 2 \mathrm{LiOH}+\mathrm{CO}_{2} \longrightarrow \mathrm{Li}_{2} \mathrm{CO}_{3}+\mathrm{H}_{2} \mathrm{O} $$ (a) If $0.500 \mathrm{~kg}$ LiOH were available, how many grams of $\mathrm{CO}_{2}$ could be consumed? (b) How many grams of water would be produced?

Key Concepts

Balanced Chemical Equations

Balanced chemical equations are equations in which the number of atoms for each element is conserved between the reactants and products. They provide the stoichiometric coefficients necessary to understand the proportionate amounts of substances involved in the reaction.

Stoichiometry

Stoichiometry is the study of the quantitative relationships between reactants and products in a chemical reaction. It involves using the balanced chemical equation to determine mole ratios, which then allow for conversion between the masses of different substances involved in the reaction.

Mole Concept

The mole concept is fundamental in chemistry as it provides a bridge between the atomic scale and macroscopic amounts of a substance. It allows chemists to count entities by relating the mass of a substance to the number of particles it contains, using Avogadro's number as a conversion factor.

Molar Mass

Molar mass is the mass of one mole of a substance, usually expressed in grams per mole. It is used to convert between the mass of a substance and the number of moles, which is essential for performing stoichiometric calculations in chemical reactions.
