How much iron can be theoretically obatined by the reduction of 1.0kg of `Fe_(2)O_(3)`?(At.wt.of Fe=56)`

Explanation

`underset(1 kg )underset(160)(Fe_(2)O_(3)) + 3H_(2) to underset(?)underset(11)(2Fe) + 3H_(2)O`
160 g of `Fe_(2)O_(3)` on reduction gives iron = 112 g
1000 g of `Fe_(2)O_(3)` on reduction will give iron
`=112/160 xx 1000 = 700`g
