from equation, 24 dm3 of o2 comes from 2 moles of h2o2.
                      3 dm3 of o2 comes from ¼ moles of h2o2
  100 cc=10^-1 dm3. therefore x/10=1/4. saupposing molarity is x)
          x=2.5M. please approve if its right

From equation 24 dm3 of o2 comes from 2 mol of h2o23dm3 of o2 comes from 1/4 moles of h2o2Now molarity is equal to(Mole/vol (ml))*1000Therefore x=(1/4*1000)/100 =2.5
