WebbDaneben kommt H2O2 aufgrund seiner bleichenden Wirkung auch zur Zahnaufhellung und als Haarfärbemittel zum Einsatz. Kommen wir nun zur großen Liste der Anwendungsmöglichkeiten von Wasserstoffperoxid. Die Liste ist zur Übersicht in die Bereiche Gesundheit/Körper und Haushalt/Reinigung gegliedert. 77 Tipps ist das Ziel. WebbSolution : *The problem indicates that the H2O2 present in the solution is 3% by mass, it means that in a 100 g of solution there is 3 g of H2O2. Molarity (M) = moles of SOLUTE / Liters of SOLUTION Let us look for the moles of solute first: (n= number of moles) n of H2O2= given mass / molar mass n= 3 g / 34.0147 g/mol = 0.088 mol of H2O2
