2Fe + 3Cl2 --> 2FeCl3 is your balanced equation. The coefficient for Cl2 is thus 3.
Note:
2Fe + 3Cl2 --> 2FeCl3
Left side of the equation:
2 Fe
6 Cl
Right side of the equation:
2 Fe
6 Cl, so your equation is balanced.

Easiest way to do these is look at the half reactions:
Fe ---> Fe+3 + 3e-
Cl2 + 2e- --> 2 Cl-
Now get the same number of electrons on both sides. To do this you need to multiply the first one by 2 and the last one by 3:
2 Fe ---> 2 Fe+3 + 6 e-
3 Cl2 + 6e- ---> 6 Cl-
Add them together and you get a balanced equation:
2 Fe + 3 Cl2 ----> 2 FeCl3

2Fe + 3Cl2 ---> 2FeCl3
OR
Fe + 1.5 Cl2 ---> FeCl3
