Question
Calculate the weight of iron which will be converted into its oxide by the action of 18g of steam on it.
- 37.3 gm
- 3.73 gm
- 56 gm
- 5.6 gm
The correct answer is: 37.3 gm
2Fe + 3H2O 
Fe2O3 + 3H2
3 ´ 18gm of steam will react with 2 ´ 56 gm of Iron
\ 18 gm of steam will convert = 
= 37.3 gm of Fe
