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

h let me think about that

under a microscope, cancer cells may look very different from normal cells. they often have different sizes and some may be larger than normal while others are smaller. cancer cells are often abnormally shaped and the control centre of the cell (the nucleus) may have an abnormal appearance.
