### Titration Problem:A 50.0 mL solution of Ca(OH)₂ with an unknown concentration was titrated with 0.340 M HNO₃. To reach the endpoint, a total of 28.4 mL of HNO₃ was required.Given that 0.00966 mol of HNO₃ are used in the titration, what quantity in moles of Ca(OH)₂ had to be present in the initial reaction?### Explanation:To solve this problem, consider the balanced chemical equation between Ca(OH)₂ and HNO₃:\[ \text{Ca(OH)}_2 + 2\text{HNO}_3 \rightarrow \text{Ca(NO}_3)_2 + 2\text{H}_2\text{O} \]This indicates that 2 moles of HNO₃ react with 1 mole of Ca(OH)₂. You can use the stoichiometric relationship between the reactants to find the initial moles of Ca(OH)₂.### Steps to Solve:1. **Identify the Moles of HNO₃:** - Provided that 0.00966 mol of HNO₃ were used in the reaction.2. **Stoichiometric Conversion:** - Since 2 moles of HNO₃ react with 1 mole of Ca(OH)₂, we can calculate the moles of Ca(OH)₂ needed initially by dividing the moles of HNO₃ by 2.3. **Calculation:** - Moles of Ca(OH)₂ = \( \frac{0.00966 \text{ mol HNO}_3}{2} = 0.00483 \text{ mol Ca(OH)}_2 \)The initial reaction required 0.00483 moles of Ca(OH)₂.
