Atomic no = no of electrons present in atom
and atomic mass = no of protons + no of neutrons
The balanced chemical equation is:
2Fe+3H2O=Fe2O3+3H2
We are given the amount of water to be used in the reaction. This will be the starting point for the calculations.
3 mol H2O ( 1 mol Fe2O3 / 3 mol H2O ) = 1 mol Fe2O3
Therefore, the correct answer is option B.
