A commonly purchased disinfectant is a 3.0% (by mass) solution of hydrogen peroxide (H2O2) in water. Assuming the density of the solution is 1.0 g/cm³, calculate the molarity and molality of H2O2.
A) Molarity: 1.0mol/L, Molality: 1.0mol/kg
B) Molarity: 3.0mol/L, Molality: 3.0mol/kg
C) Molarity: 3.0mol/L, Molality: 1.0mol/kg
D) Molarity: 1.0mol/L, Molality: 3.0mol/kg
