**Passage 3:** For the same solution, what is the molality? — Mole Concept and Some Basic Concepts of Chemistry Chemistry Question
Question
**Passage 3:** For the same $10\% \text{ (w/w) } NaOH$ solution, what is the molality?
Answer: A
💡 Solution & Explanation
$m = \frac{1000 \times \%}{MW \times (100 - \%)} = \frac{1000 \times 10}{40 \times 90} = \frac{1000}{360} \approx 2.77 \text{ m}$.
