A 2.30 gram sample of iron combines with chlorine gas to form an iron chloride with the weight of 7.25 grams. what is the weight of chlorine added?

• chemistry -

Wouldn't that be 7.25-2.30 = ?
However, the numbers don't add up. 2.30 g Fe should form a 5.22 g sample if FeCl2 or 6.68 g sample for FeCl3.
