Which of the following statements is/are correct for of solution? — Mole Concept and Some Basic Concepts of Chemistry Chemistry Question

💡 Solution & Explanation

$\text{moles } Ca(NO_3)_2 = 0.1 \times 0.1 = 0.01$. <br>Dissociation: $Ca(NO_3)_2 \rightarrow Ca^{2+} + 2NO_3^-$. <br>$\text{moles } Ca^{2+} = 0.01$; $\text{moles } NO_3^- = 0.02$. <br>$\text{Total moles of ions} = 0.01 + 0.02 = 0.03 \text{ mol}$. <br>$[NO_3^-] = 0.02 / 0.1 = 0.2 \text{ M}$.
