Answer:

Sorry. #"1 mol Fe" = 3.17 × 10^23color(white)(l) "atoms Fe"#

Explanation:

You don’t need the atomic mass of #"Fe"#.

All you need to know is that #"1 mol" = 6.022 × 10^23color(white)(l) "atoms"#.

Then

#0.526 color(red)(cancel(color(black)("mol Fe"))) × (6.022 × 10^23color(white)(l) "atoms Fe")/(1 color(red)(cancel(color(black)("mol Fe")))) = 3.17 × 10^23 color(white)(l)"atoms Fe"#
