What is the percent of hydrogen peroxide in the solution when 5.02g of H2O2 solution reacts to produce 0.153g of H2O? 2H2O2 (l) → 2H2O (l) + O2 (g)

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

a) 3%

b) 5%

c) 30%

d) 50%

(if your answer doesn't match one of the choices, that's probably because there was a typo in the original question, and I fixed it to make sense. it was: "...5.02g of H2O2 solution reacts to produce 0.153g of H2O2?..." which didn't make very much sense.)

The activation energy for the decomposition of hydrogen peroxide is 55.0 kJ/mol. When the reaction is catalyzed by the enzyme catalase, it is 11.00 kJ/mol. 2H2O2(aq) → 2H2O(l) + O2(g) Calculate the temperature that would cause the nonenzymatic catalysis to proceed as rapidly as the enzyme-catalyzed decomposition at 20.0°C. Assume the frequency factor, A, to be the same in both cases. Report your answer to 3 significant figures.
