- D \(1 \mathrm{~mL}\) of \(\mathrm{H}_2 \mathrm{O}_2\) will give 1 mole of \(\mathrm{O}_2\) at STP
Answer & Solution
Correct Answer
(A) \(1 \mathrm{~mL}\) of \(\mathrm{H}_2 \mathrm{O}_2\) will give \(100 \mathrm{~mL}\) of \(\mathrm{O}_2\) at STP
Step-by-step Solution
Detailed explanation
100 volume \(\mathrm{H}_2 \mathrm{O}_2\) solution indicates \(1 \mathrm{~mL}\) of the \(\mathrm{H}_2 \mathrm{O}_2\) solution will give \(100 \mathrm{~mL}\) of \(\mathrm{O}_2(g)\) at STP.
