32 g of

\text{KMnO}_4

are allowed to react with a mixture of 4 g of KCl and mg of KBr in presence of concentrated

\text{H}_2\text{SO}_4

. If the oxidizing agent is just sufficient to react with both halides completely to liberate halogen, what is the value of

m

? (Atomic mass: K = 39, Br = 80)
