Iron reacts with chlorine gas to form iron (III)
chloride. How many grams of iron(III) chloride are formed from 112g
of iron?
Wondering if I did this right!
First balance: 3Fe + Cl ---> FeCl3 or 3Fe +
3Cl ---> FeCl3 *Not Sure*
Second Convert grams to mols: 112g/Fe to Mols =
2 mol/fe
Third Convert mols to gram: 2 mol/Fe *
162.204g/FeCl3 / 3 mol/Fe = 108.136 g/FeCl/3 round
108grams/FeCl3
