Find the mole fraction of methanol () in a solution containing of methanol and of water. — Mole Concept and Some Basic Concepts of Chemistry Chemistry Question

💡 Solution & Explanation

$\text{moles methanol} = 32 / 32 = 1 \text{ mol}$. <br>$\text{moles water} = 36 / 18 = 2 \text{ mol}$. <br>$\chi = 1 / (1 + 2) = 1/3 \approx 0.33$.
