### Problem StatementA different hydrate of nickel(II) chloride, $ \text{NiCl}_2 \cdot X \text{H}_2\text{O} $, decomposes to produce 45.5% water. **Task:** Calculate the water of crystallization $(X)$, and write the formula for the hydrate.### Solution Steps1. **Identify the Given Information:** - The compound is nickel(II) chloride hydrate, $ \text{NiCl}_2 \cdot X \text{H}_2\text{O} $. - The percentage of water in the compound is 45.5%.2. **Calculate the Molar Masses:** - Molar mass of $ \text{NiCl}_2 $ = 58.69 (Ni) + 2(35.45) (Cl) = 129.59 g/mol - Molar mass of $ \text{H}_2\text{O} $ = 18.02 g/mol3. **Set Up the Equation:** \[ \frac{X \times 18.02}{129.59 + X \times 18.02} \times 100 = 45.5 \]4. **Solve for $X$:** - Rearrange and solve the equation for $X$.5. **Write the Formula:** - Once $X$ is found, write the complete hydrate formula as $ \text{NiCl}_2 \cdot X \text{H}_2\text{O} $.### Additional Information- **Water of Crystallization:** Refers to the fixed number of water molecules chemically bonded within a crystalline structure of a compound.- **Hydrates:** Compounds that include water molecules within their crystalline structures, often affecting the substance’s properties.This exercise involves calculating the stoichiometry of a hydrate and understanding its composition based on given percentages.
