The concentration of a hydrogen peroxide solution is sometimes expressed as "volume percent," which here means the number of 100 ml volumes of oxygen gas (under stp) liberated from 100 ml of the given solution upon complete decomposition of hydrogen peroxide into water and oxygen. what form would the calculation take if the result of titration in the present experiment were to be expressed in this way?
