Approved Tutor Answer8 Years agoAccording to the question, for x mole of Fe, x/4 mole Fe3+ and 3x/4 mole of Fe2+ are present in the sample.Balancing the charge, (x/4)*3+(3x/4)*2=2*1We get x=8/9.So the compound is Fe8O9 or Fe8/9O.Thanks for reading

Let amount of Fe(+2)=3a. And, Fe(+3)=a. Then ,total (+)charge = total (-) charge-->. 3(a) +2(3a)=2. --> a = 2÷9 --> since total Fe = 3a + a = 4a --> Fe = 8÷9= .888
