For of a solution (density ), which is/are correct? — Mole Concept and Some Basic Concepts of Chemistry Chemistry Question

💡 Solution & Explanation

A) $20\%$ of $100\text{g} = 20\text{g}$. B) $n = 20/40 = 0.5$. C) $\text{Solvent} = 80\text{g}$. $m = 0.5/0.08 = 6.25\text{ m}$. D) $\text{Volume} = 100/1.2 = 83.33\text{ mL}$. $M = 0.5/0.0833 \approx 6\text{ M}$. [3, 4]
