Answer:

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.
