The density of a solution of is . The molality of the solution is: — Mole Concept and Some Basic Concepts of Chemistry Chemistry Question

💡 Solution & Explanation

$\text{Mass of 1 L solution} = 1100 \text{ g}$. <br>$\text{Mass of solute (MW=106)} = 106 \text{ g}$. <br>$\text{Mass of solvent} = 1100 - 106 = 994 \text{ g} = 0.994 \text{ kg}$. <br>$\text{Molality} = 1 / 0.994 \approx 1.006 \text{ m}$. (Closest is 1.058 or 1.00 depending on rounding).
