Base your answer to this question on the information below.
hydrogen peroxide, h2o2 , a water-soluble campound. the concentration of an aqueous hydrogen peroxide solution that is 3% by mass h2o2 is used as an antiseptic. when the solution is poured on a small cut in the skin, h2o2 reacts according to the balanced equation below.
2h2o2 -> 2h2o+ o2
calculate the total mass of h2o2 in 20.0 grams of an aqueous h2o2 solution that is used as an antiseptic.
1. (34)(20.0)g
2. (34)(0.03)g
3. (20.0)(0.03)g
4. (20.0)(3)g
