Explanation / Answer

Part B:

mol Fe= 2.912g/55.8457g/mol= 0.052143674 mol

mol Cl= mol Fe x 3= 0.156431023mol ----> mass Cl= 0.156431023mol x 35.453g/mol= 5.546g

mass FeCl3= mass Cl + mass Fe= 5.546 + 2.912= 8.458g

Part C:

mol Cl= 2.829g/35.453g/mol= 0.079795785 mol

mol Cl= mol Fe x 3 ---> mol Fe= mol Cl/3= 0.026598595 mol Fe

mass Fe=  0.026598595 mol x 55.8457g/mol= 1.485g

mass FeCl3= mass Fe + mass Cl= 1.485g + 2.829g= 4.314g
