Options:
  • A \(1 \mathrm{~mL}\) of \(\mathrm{H}_2 \mathrm{O}_2\) will give \(100 \mathrm{~mL}\) of \(\mathrm{O}_2\) at STP
  • B \(1 \mathrm{~L}\) of \(\mathrm{H}_2 \mathrm{O}_2\) will give \(100 \mathrm{~mL}\) of \(\mathrm{O}_2\) at STP
  • C \(1 \mathrm{~L}\) of \(\mathrm{H}_2 \mathrm{O}_2\) will give \(22.4 \mathrm{LO}_2\) at STP
  • D \(1 \mathrm{~mL}\) of \(\mathrm{H}_2 \mathrm{O}_2\) will give 1 mole of \(\mathrm{O}_2\) at STP

The correct answer is: \(1 \mathrm{~mL}\) of \(\mathrm{H}_2 \mathrm{O}_2\) will give \(100 \mathrm{~mL}\) of \(\mathrm{O}_2\) at STP
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.
