"How many moles of iron atoms are in 1.5 ×10e24 atoms iron?"
you know that you have 1.5x10e24 atoms of iron then you want to change it from atoms to moles
moles equal 6.022e23 atoms which is avogadro's number
so its 1.5x10^24 * 1/6.022x10^23
its 1.5x10^24/6.022x10^23

To add onto what dominus said
1.5x10^24 / 6.022x10^23 = 2.49x10^-1
answer should be .249 moles

2.49 moles of iron atoms
take the # of atoms and divide it by avogardo's number which is 6.022e23 or 6.022 x 10^23
