.25 mol Fe* 6.022*10^23 molecules/mol= 1.5*10^23

There are 6.023 x 10^23 molecules (actually atoms, in the case of a monatomic element like iron) in one mole of any element or compound, so just divide that by 4 and you'll have your answer. 1.506 x 10^23, approximately. A molecule and an atom of iron mean the same thing, so it's not a trick question.

If this is a trick question the answer is zero. ;)
If you want "atoms" of Fe the answer is:
0.25 moles Fe x (6.022 x 10^23 atoms/mole) = 1.51 x 10^23 atoms of Fe

use avogrados number to find the molecules

no. of molecules=no. of moles x avogadro's number
given 0.25 moles of Fe
no. of molecules=0.25 x 6.02x10^23
just type it on your scientific calculator please... i dont have one around...
