A sample of MnSO_(4). 4H_(2)O is strongly heated in air. The residue ( Mn_(3)O_(4)) left was dissolved in 100 mL of 0.1NFeSO_94) containing dil. H_(2)SO_(4) . This solution was completely reacted with 50 mL of KMnO_(4) solution. 25 mL of this KMnO_(4) solution was completely reduced by 30 mL of 0.1N FeSO_(4) solution. Calculate the amount of MnSO_(4).4H_(2)O in sample.

Volume of 0.1M ferrous oxalate solution required to react completely with 60ml of 0.1N acidified KMnO_(4) solution
