What is the percent of hydrogen peroxide in the solution when 5.02g of h2o2 solution reacts to produce 0.153g of h2o2? 2h2o2 (l) → 2h2o (l) + o2 (g) mass percent = (mass of solute/mass of solution)*100

The %  of hydrogen peroxide in the solution is  3 %

         Explanation

mass percentage is  away of representing the concentration  of component in a mixture.  it is calculated as below;

Mass  percent = ( mass of solute/ mass of solution )  x 100

,mass of solute  = 0.153 g

mass of solution= 5.02 g

mass  percentage is therefore= 0.153 g /5.02 g  x 100 =  3%
