Strategy:
 Use the equivalent concept to relate the impure barium permanganate sample to the known volume strength of . Purity is the fraction of total mass represented by the pure reacting species calculated from stoichiometry.

Step 1: Find Normality of } \ce{H2O2}

Equivalents of .

Step 2: Calculate mass of pure } \ce{Ba(MnO4)2}
Eq of .
n-factor of  (each  is , and there are two).
Molar mass . Equivalent mass .

Step 3: Calculate percentage purity
