Question

Calculate mass of iron which will be converted into its oxide

Answer 1

Answer:

Eg. Calculate weight of iron which will be converted into its oxide(Fe3O4) by action of 18g steam on it.

moles of steam

moles of steam =\frac{18g}{18g/mol}=1 mole[/tex]

From the balanced equation:

4 moles of steam react with =3 moles of iron to give ferric oxide.

1 mole of steam react with = of iron to give ferric oxide.

Mass of iron=
