Hydrogen peroxide is a powerful oxidizing agent in concentrated solution in rocket fuels and in dilute solution as a hair bleach. An aqueous solution H202 is 30.0% by mass and has a density of 1.11g/mL. Calculate its: (a) molality (b) mole fraction of H202 (c) molarity (a) From mass % to molality (mol/kg solvent): (b) From mass % to mole fraction [mol solute/(mol solute + mol solvent)]: (c) From mass % and density to molarity:
