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)

Given:

Mass of H2O2 solution = 5.02 g

Mass of H2O2 = 0.153 g

To determine:

The % H2O2 in solution

Explanation:

Chemical reaction-

2H2O2(l) → 2H2O(l) + O2(g)

Mass % of a substance in a solution = (Mass of the substance/Mass of solution) * 100

In this case

% H2O2 = (Mass H2O2/Mass of solution)* 100 = (0.153/5.02)*100 = 3.05%

Ans: % H2O2 in the solution = 3.05%
