PROBLEM 3.10 After lithium hydroxide is produced aboard the space shuttle by reaction of $\mathrm{Li}_{2} \mathrm{O}$ with $\mathrm{H}_{2} \mathrm{O}$ (Problem $\left.3.9\right)$, it is used to remove exhaled carbon dioxide from the air supply. How many grams of $\mathrm{CO}_{2}$ can $500.0 \mathrm{~g}$ of $\mathrm{LiOH}$ absorb? $$ \mathrm{LiOH}(s)+\mathrm{CO}_{2}(g) \longrightarrow \mathrm{LiHCO}_{3}(s) $$

Key Concepts

Mass-to-Mole Conversion

Mass-to-mole conversion is the method of converting the mass of a substance into moles by dividing by its molar mass. This calculation is a key step in stoichiometry, as it allows one to determine the number of particles involved in a reaction from a given mass.

Mole Concept

The mole concept is a fundamental principle in chemistry that allows chemists to count particles like atoms or molecules by converting them into measurable amounts of substance using Avogadro's number. This concept underpins the quantitative aspects of chemical reactions and stoichiometric calculations.

Stoichiometry

Stoichiometry involves using the balanced chemical equation to determine the quantitative relationships between reactants and products. It is crucial for calculating how much of a product can be generated from a given amount of reactant by relating the moles of substances through the coefficients in the equation.

Molar Mass

Molar mass is the mass of one mole of a substance, expressed in grams per mole. It serves as a conversion factor between the mass of a substance and the number of moles, which is essential for linking macroscopic measurements with molecular-scale processes.
