Chemistry Question on Mole concept and Molar Masses

From the given reaction 2KMnO4+3H2SO4+5H2O2→K2SO4+2MnSO4+8H2O+5O22KMnO_{4} + 3H_{2}SO_{4} + 5H_{2}O_{2} \rightarrow K_{2}SO_{4} + 2MnSO_{4} + 8H_{2}O + 5O_{2}
Find the normality of H2O2H_{2}O_{2} solution, if 20mL20\text{mL} of it is required to react completely with 16mL16\text{mL} of 0.02M0.02\text{M}, KMnO4KMnO_{4} solution. (Molar mass of KMnO4=158g mol−1KMnO_4 = 158\text{g mol}^{-1})
