Hydrogen peroxide is an extremely unstable liquid. consequently, it is only commercially available as an aqueous solution. for this experiment we will use reagent grade h2o2 which is a 30.0% (w/w) solution the unit (w/w) denotes a weight/weight percentage (solute/solution) 30.0% (w/w) solution 30.0 g h2o2 per 100 g solution density of 30.0% h2o2 solution 1.11 g/ml i. what is the concentration (in m) of 30.0% (w/w) h2o2? i. how many milliliters (ml) of 30.0% (w/w) h2o2 solution are needed to prepare 50.0 ml of3.60 m h202 solution?
