Chapter 4, Problem 4.16PAE

4.16 Many metals react with halogens to give metal halides. For example, iron reacts with chlorine to give iron(II) chloride, FeCl₂:

   $\text{Fe}\left(s\right)+{\text{ Cl}}_{\text{2}}\left(g\right) \to {\text{FeCl}}_{\text{2}}\left(s\right)$

Beginning with 10.0 g iron, what mass of Cl₂, in grams, is required for complete reaction? What quantity of FeCl₂, in motes and in grams, is expected?
