How many moles of fe2o3 will be produced from 18.0 g of fe assuming o2 is available in excess

0.161 moles of Fe₂O₃

Explanation:

Given data:

Mass of Fe  = 18g

Unknown:

Number of moles  = Fe₂O₃

Solution:

The number of moles of a substance is given as:

          Number of moles  =

To solve this problem, we should understand that oxygen gas is given in excess and iron is the limiting reactant.

The equation of the reaction is given below;

            4Fe   +   3O₂     →    2Fe₂O₃

First, find the number of moles of the known specie which is iron;

         Number of moles of Fe  =    = 0.32mole

From the balanced reaction equation;

          4 moles of Fe will produce 2 moles of Fe₂O₃

        0.32 moles of Fe will produce    = 0.161 moles of Fe₂O₃
