Explanation:
The molar mass of H2O2 is 34.0147 g/mol and the density of the solution is 1.000 g/mL.
30% W/V H2O2 means that for each 100 mL of solution there are 30 g of hydrogen peroxide. The molarity is obtained as moles of solute in 1 L (1000 mL) of solution. In your case, 1 L of solution contains 300 g of H2O2 (PM=34.01 g/mol). Therefore, the molarity is (300 g/34.01 g/mol) = 8.82 M.
