The density of a aqueous solution of is . What is the molarity of the solution? — Mole Concept and Some Basic Concepts of Chemistry Chemistry Question

💡 Solution & Explanation

$\text{Mass of 2 molal solution} = \text{Mass solute} + \text{Mass solvent} = (2 \times 40) + 1000 = 1080 \text{ g}$. <br>$\text{Volume of solution} = \frac{1080}{1.08} = 1000 \text{ mL} = 1 \text{ L}$. <br>$\text{Molarity} = \frac{2 \text{ mol}}{1 \text{ L}} = 2 \text{ M}$.
