a) What mass of a 30% (w/w) hydrogen peroxide solution is required to provide the 3.06g H2O2 contained in 25.0 mL of a 3.6 M solution. (a w/w solution means g solute/100 g solution)?    b) What volume of 30.0% hydrogen peroxide solution is required to provide the mass above in the previous question? (density30.00% H2O2 = 1.11 g/mL)?
