Question:
1 mL of 30 % (w/V) $H_2O_2$ solution at STP gives 100 mL of oxygen gas. The volume strength of $H_2O_2$ (in V) is:
1 mL of 30 % (w/V) $H_2O_2$ solution at STP gives 100 mL of oxygen gas. The volume strength of $H_2O_2$ (in V) is:
Show Hint
"Volume strength" is literally the number of volumes of $O_2$ released per unit volume of solution.

Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Step 1: Concept
Volume strength of $H_2O_2$ is the volume of oxygen gas produced at STP per 1 mL of the solution.
Step 2: Analysis
The problem states that 1 mL of this solution gives 100 mL of oxygen gas at STP. By definition, this is a 100-volume solution.
Step 3: Conclusion
The volume strength is 100 V.
Final Answer: (B)
