Well, since you only have 1 molecule of Fe in Fe2O3, which consists of 2 atoms, it, therefore, follows that you should have: 25 x 2 = 50 atoms of Fe in 25 molecules of Fe2O3.

What does Fe2O3 mean? Well, it is a compound called "Iron Oxide". Right?. It consists of 2 elements:

Fe(Iron) and O(Oxygen). The 2 in front of Fe means 2 atoms of iron stick together to form 1 molecule of Iron in this compound, Fe2O3. Similarly, 3 atoms of Oxygen stick together to form 1 molecule of Oxygen in this particular compound, Fe2O3. Then 1 molecule of Iron, Fe2, sticks to 1 molecule of Oxygen, O3, and that combination forms a compound called "Iron Oxide", Fe2O3 !!.

Wow! you are smart! I'm sure GALDOSHN understands perfectly.  Five stars from me.

 

I'm using your post as an example for a sophisticated,  educational  post that meanders everywhere except toward an explanation for the question. 

 

It's easy to see why the dumb get dumber.
