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..- shiyao85

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 *...- shiyao85
