# Question #1b54b

This problem is a one step conversion between grams and moles using a conversion factor of 1 mole = atomic mass unit of the element.

$223.2 g F e x \frac{1 m o l F e}{55.85 g F e} =$

In this case we get the mass of Iron (Fe) of 55.85 from the periodic table.

To calculate, the grams of Fe will cancel and we will be left with the moles of Fe as the final outcome.

$\frac{223.2}{55.85} = 3.996 m o l F e$
