The molarity of a solution of is: — Mole Concept and Some Basic Concepts of Chemistry Chemistry Question
Question
The molarity of a $0.2\text{ N}$ solution of $Na_2CO_3$ is:
Answer: A
💡 Solution & Explanation
$\text{Molarity} = \text{Normality} / \text{n-factor}$. <br>For $Na_2CO_3$, $\text{n-factor (total cationic charge)} = 2$. <br>$M = 0.2 / 2 = 0.1\text{ M}$. [9, 10]
