Which of the following is/are correct about "20 volume" solution? — Mole Concept and Some Basic Concepts of Chemistry Chemistry Question

💡 Solution & Explanation

$\text{Vol. strength} = 11.2 \times M \Rightarrow M = 20 / 11.2 \approx 1.78 \text{ M}$. <br>$\text{Normality} = M \times 2 \approx 3.57 \text{ N}$. <br>$\text{Strength} = M \times 34 = 1.78 \times 34 \approx 60.7 \text{ g/L}$. <br>The name "20 volume" means $1 \text{ L}$ solution yields $20 \text{ L } O_2$ at STP.
