How many milligrams of calcium chloride dihydrate $\left(\mathrm{CaCl}_2 \cdot 2 \mathrm{H}_2 \mathrm{O}\right.$, molecular weight $=147 \mathrm{~g} / \mathrm{mol}$ ) are needed to prepare $1500 \mathrm{~mL}$ of solution containing $5 \mathrm{mEq} /$ liter $\mathrm{Ca}^{+2}$ ?

Key Concepts

Hydration in Chemical Compounds

Hydration in chemical compounds refers to the incorporation of water molecules into the crystalline structure of a compound. This is denoted by a dot and the number of water molecules in the chemical formula, and these water molecules contribute to the overall molar mass, affecting stoichiometric calculations used in preparing solutions.

Unit Conversion

Unit conversion is the practice of converting quantities from one system of measurement to another, such as from grams to milligrams or milliliters to liters. Accurate unit conversion is essential for maintaining consistency in calculations and ensuring that the final solution meets the specified conditions.

Stoichiometry

Stoichiometry involves the calculation of the quantitative relationships among reactants and products in chemical reactions. It provides the framework for converting between mass, moles, and the number of ions, ensuring accurate formulation of solutions based on molecular compositions.

Milliequivalents

Milliequivalents (mEq) quantify the chemical reactivity of ions in solution by considering both the concentration and the ion’s valence. They are used to express the amount of a substance in terms of its capacity to react, which is essential when preparing solutions with precise ionic strengths.

Molar Mass

Molar mass is the mass of one mole of a substance, calculated by summing the atomic masses of all atoms in its molecular formula. It serves as a conversion factor between the amount in moles and the mass (in grams or milligrams) of a compound, which is crucial in solution preparation.
