of and of were dissolved in water to have of solution. The molarity of ions is: — Mole Concept and Some Basic Concepts of Chemistry Chemistry Question

💡 Solution & Explanation

$\text{Moles of } Cl^- \text{ from } HCl = 0.2$. <br>$\text{Moles of } Cl^- \text{ from } CaCl_2 = 2 \times 0.1 = 0.2$. <br>$\text{Total moles} = 0.4$. $\text{Molarity} = 0.4 / 0.5 = 0.8\text{ M}$.
