Answer:

The atomic mass of iron (Fe) is 55.85 amu. The atomic mass of radium (Ra) is 226 amu. One mole of atoms of any element contains 6.022 X 1023 atoms, regardless of the type of element.

Iron (Fe) has an atomic mass of 55.845 g/mol. So if you have 13.2 grams, you have 13.2/55.845 mol = 0.2364 moles.

Hope this helps!
