3 g of pyrolusite ore was treated with 20g of pure ammonium sulphate and dil sulphuric acid. After the reaction solution was diluted to 500 ml. 50 ml of dilute solution required 10 ml of 0.1 N K2Cr2O7 solution. What is the amount of ferrous ammonium sulphate in the solution which is neutralised by K2Cr2O7 solution ?
