A sample of is labeled as . What is its volume strength? — Mole Concept and Some Basic Concepts of Chemistry Chemistry Question
Question
A sample of $H_2O_2$ is labeled as $10\% \text{ (w/v)}$. What is its volume strength?
Answer: 32.9
💡 Solution & Explanation
$10\% w/v = 100 \text{ g/L}$. <br>$\text{Molarity} = \frac{100}{34} = 2.94 \text{ M}$. <br>$\text{Volume strength} = 11.2 \times 2.94 \approx 32.9$.
