Hydrogen peroxide (H2O2) is decomposed according to the following reaction:
2H2O2 (l) ¡÷ 2H2O (l) + O2 (g)
If 6.00 g of aquesous solution containing hydrogen peroxide was decomposed after heating, the mass of oxygen gas collected is 2.40 g, what is the mass percentage of H2O2 in the original solution?
