The mole fraction of the solute in a aqueous solution is: — Mole Concept and Some Basic Concepts of Chemistry Chemistry Question

💡 Solution & Explanation

$1\text{ m}$ solution means $1\text{ mole}$ solute in $1000\text{ g}$ water. $\text{Moles of water} = 1000/18 = 55.55$. $\chi_{\text{solute}} = 1 / (1 + 55.55) = 1 / 56.55 \approx 0.0177$.
