You have quoted a 2 mol quantity, this is 2xx6.022xx10^23 Fe^(3+) ions.

Explanation:

You can use the mole as you would any other collectve number, "dozens, scores, grosses, centuries". If I have one mole of stuff there are 6.022xx10^23 individual items of that stuff.

You have 2 mol of Fe^(3+) ions, and thus 12.066xx10^23 Fe^(3+) ions.
