A commercial sample of \(\mathrm{H}_2 \mathrm{O}_2\) marked as 100 volume hydrogen peroxide means
  1. \(1 \mathrm{~mL}\) of \(\mathrm{H}_2 \mathrm{O}_2\) will give \(100 \mathrm{~mL}\) of \(\mathrm{O}_2\) at STP
  2. \(1 \mathrm{~L}\) of \(\mathrm{H}_2 \mathrm{O}_2\) will give \(100 \mathrm{~mL}\) of \(\mathrm{O}_2\) at STP
  3. \(1 \mathrm{~L}\) of \(\mathrm{H}_2 \mathrm{O}_2\) will give \(22.4 \mathrm{LO}_2\) at STP
  4. \(1 \mathrm{~mL}\) of \(\mathrm{H}_2 \mathrm{O}_2\) will give 1 mole of \(\mathrm{O}_2\) at STP

Solution

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.
