Which conversion factor do you use first to calculate the number of grams of FeCl3 produced by the reaction of 30.3 g of Fe with C12? (What would be your first step in the bracket/train tracks?)
2Fe + 3Cl2 --> 2FeCl3

1) 1 mol Fe/ 55.845 g Fe
2) 3 mol Cl2/ 2 mol Fe
3) 35.453 g Cl2/ 1 g Fe
4) 162.2 g FeCl3/ 2 mol FeCl3
