An aqueous solution contains $5.00 \mathrm{~g}$ of calcium chloride, $\mathrm{CaCl}_{2}$, per liter. What is the molarity of $\mathrm{CaCl}_{2}$ ? When calcium chloride dissolves in water, the calcium ions, $\mathrm{Ca}^{2+},$ and chloride ions, $\mathrm{Cl}^{-},$ in the crystal go into the solution. What is the molarity of each ion in the solution?

Key Concepts

Molarity

Molarity is a measure of the concentration of a solute in a solution, defined as the number of moles of solute per liter of solution. It is a fundamental concept in chemistry used to express how diluted or concentrated a solution is and is essential for quantifying the amount of a substance present in a given volume of solvent.

Molar Mass

Molar mass represents the mass of one mole of a substance, typically expressed in grams per mole. It is used to convert between the mass of a substance and the number of moles, allowing the calculation of moles present in a given mass of a compound, which is crucial for stoichiometric calculations.

Dissociation of Ionic Compounds

Dissociation of ionic compounds in water refers to the process whereby ionic compounds separate into their individual ions when dissolved in water. This concept is important because the stoichiometry of the dissociation reaction determines the relationship between the concentration of the compound and the concentrations of its constituent ions in solution.

Stoichiometry

Stoichiometry involves the quantitative relationships between reactants and products in chemical reactions, including dissolution processes. It is used to determine the proportion of each ion produced when an ionic compound dissociates, based on the balanced chemical equation for the dissolution reaction.
