(JEE Main) Density of a 1M solution of glucose is 1.18 g/mL. The molality is: — Mole Concept and Some Basic Concepts of Chemistry Chemistry Question

💡 Solution & Explanation

$\text{Mass of 1L} = 1180 \text{ g}$. $\text{Solute} = 180 \text{ g}$. $\text{Solvent} = 1000 \text{ g} = 1 \text{ kg}$. $\text{Molality} = 1 / 1 = 1.0 \text{ m}$.
