The number of ions in of is . Find the value of . — Mole Concept and Some Basic Concepts of Chemistry Chemistry Question

💡 Solution & Explanation

$\text{moles } CaCl_2 = 111 \times 10^{-3} / 111 = 0.001 \text{ mol}$. <br>$\text{moles } Cl^- = 2 \times 0.001 = 0.002 \text{ mol}$. <br>$\text{Number of ions} = 0.002 \times 6.022 \times 10^{23} \approx 1.2 \times 10^{21}$. <br>Thus, $x = 1.2$.
