# What is the formula mass of FeCl2?

## What is the formula mass of FeCl2?

126.751 g/mol
Iron(II) chloride/Molar mass

## What is the charge of FeCl2?

+2
Since the oxidation number for Cl- is always -1, and there are two Cl- in the formula FeCl2 (total negative charge = -2), then Fe must have an oxidation number of +2 to balance the 2 Cl-. Cl-(aq): -1. Since iron is in the oxidation state +2, the compound is called iron (ii) chloride.

What is the compound name of FeCl?

Iron trichloride
Iron(III) chloride
Iron(III) chloride/IUPAC ID

### How do you find the empirical formula?

Calculate the empirical formula.

1. In any empirical formula problem you must first find the mass % of the elements in the compound.
2. Then change the % to grams.
3. Next, divide all the masses by their respective molar masses.
4. Pick the smallest answer of moles and divide all figures by that.

### Where does the dihydrate FECL 2 H 2O 2 crystallize?

The dihydrate, FeCl 2(H 2O) 2, crystallizes from concentrated hydrochloric acid. The dihydrate is a coordination polymer. Each Fe center is coordinated to four doubly bridging chloride ligands. The octahedron is completed by a pair of mutually trans aquo ligands.
