Calculate the weight of iron which will be converted into its oxide (F

1.	Calculate the weight of iron which will be converted into its oxide (Fe_(3)O_(4)) by the action 18 g of steam on it.
Answer» Solution :Chemical equation for the reaction is : `underset(underset("= 168 G= 73 g")(3xx56"" 4 xx 18))(3Fe+4H_(2)O(g))rarrFe_(3)O_(4)(s)+4H_(2)(g)` 72 g of steam `(H_(2)O)` react with iron = 168 g 18 g of steam `(H_(2)O)` react with iron `= (168xx18)/(72)=42G`.
