A solution of glucose () is . The density of the solution is . The molality of the solution is: — Mole Concept and Some Basic Concepts of Chemistry Chemistry Question

💡 Solution & Explanation

In $100 \text{ g}$ solution, solute $= 10 \text{ g}$ and solvent $= 90 \text{ g}$. <br>$\text{Moles of glucose} = 10 / 180 = 0.0555 \text{ mol}$. <br>$\text{Molality} = \frac{0.0555 \text{ mol}}{0.09 \text{ kg}} \approx 0.617 \text{ m}$.
