    Weight percent and concentration problem

    So have to convert the total volume to mass rite? assume the density to be 1 for all the solute also rite? because all of them are quite dilute..

    Weight percent and concentration problem

    Conversion of weight percent to molarity *Cw=(10×Mw×M)/ρ Where Cw is weight percent Mw is molar mass M is molarity ρ is density of the solution Assumption: -No reaction between ammonium hydroxide and hydrogen peroxide -Hydrogen peroxide Density = 1.44g/mL Cw = 31wt% Mw = 34g/mol From *...

    Weight percent and concentration problem

    the question is at below. 320ml of 29wt% of ammonium hydroxide 1210ml of 31wt% of hydrogen peroxide 30190ml of water mixed together. What is the concentration of ammonium hydroxide and hydrogen peroxide now? Is there any reaction occurs between them?
