Question
A solution of $H_2O_2$ is labeled as "20 Volume". Its strength in g/L is approximately:
Answer: A
π‘ Solution & Explanation
Volume strength = $11.2 \times \text{Molarity}$. <br>Molarity = $20 / 11.2 = 1.785 M$. <br>Strength (g/L) = $\text{Molarity} \times \text{Mw} = 1.785 \times 34 \approx 60.7$ g/L. [4, 14]
