Calculate the molarity (mol/L) of a 5% hydrogen peroxide (H2O2) solution. (5% indicates there are 5 g solute per 100 g solvent.) The molar mass of hydrogen peroxide is 34.01 g/mol. Assume the density of water is 1 g/mL. Report your answer to 2 decimal places.

An aqueous solution of hydrogen peroxide has a concentration of 0.882 M. What is its concentration in mass percent? The density of the solution is 1.02 g/mL.

mole to mole ratios of O2 to H2O2 for the calculation to find the moles and therefore the mass of H2O2 originally present in the store-bought solution. With the initial mas of the store bought solution, the mass percent of hydrogen peroxide in the sample can be determined. The molar mass of H2O2 (34.0 g/mol) and the density of the store-bought solution (1.02 g/mL). mass of solute x 100 = mass % of H2O2
