Answer» `4//5 ` `5//4` ` 3//4` `5//3` Solution :`2KMnO_(4)+ 10FeSO_(4) +8H_(2)SO_(4) RARR K_(2) SO_(4) +2MnSO_(4)+5Fe_(2)(SO_4)_(3)+8H_2O` 10MOLES g `FesO_4` requires 2 MOLES of `KMnO_4` 1 MOLE of `FeC_(2)O_4` require = 1/5 moles of `KMnO_4` `6KMnO(4) +10FeC_(2)O_(4)+24H_(2)SO_(4) rarr 3K_2SO_(4) + 6MnSO_(4) +5Fe_(2)(SO_4)_(3)+20CO_(2)+24H_(2)O` 10 mole of `FeC_(2)O_(4)` require = 6 mole of `KMnO_4` 1 mole of `FeC_(2)O_4 ` requires `=6/10 =3/5` Total moles of `KMnO_(4) ` require `=1/5+3/5 =4/5`
