# Actinium(III) Fluoride [AcF3] Molecular Weight Calculation

The molecular weight of Actinium(III) fluoride [AcF3] is 283.995209489.

Actinium(III) fluoride [AcF3] is an inorganic compound of two elements: Actinium (Ac) and Fluorine (F). The molecular weight of Actinium(III) fluoride is 283.995209489 which can be calculated by adding up the total weight (atomic weight multiplied by their number) of Actinium and Fluorine.

# CALCULATION PROCEDURE: Actinium(III) fluoride [AcF3] Molecular Weight Calculation

Step 1: Find out the chemical formula and determine constituent atoms and their number in an Actinium(III) fluoride molecule.
You will know different atoms and their number in an Actinium(III) fluoride molecule from the chemical formula. The chemical formula of Actinium(III) fluoride is [AcF3]. From the chemical formula, you can find that one molecule of Actinium(III) fluoride has one Actinium (Ac) atom and three Fluorine (F) atoms.

Step 2: Find out the atomic weights of each atom (from the periodic table).

Atomic weight of Actinium (Ac): 227 (Ref: Jlab-ele089, Lanl-89, Nist-89)
Atomic weight of Fluorine (F): 18.998403163 (Ref: Pubchem-9, Ciaaw-fluorine)

Step 3: Calculate the total weight of each atom in an Actinium(III) fluoride molecule by multiplying its atomic weight by its number.

Number of Actinium (Ac) atoms in Actinium(III) fluoride: 1
Atomic weight of Actinium (Ac): 227
Total weight of Actinium(III) atoms in Actinium(III) fluoride: 227 x 1 = 227

Number of Fluorine (F) atoms in Actinium(III) fluoride: 3
Atomic weight of Fluorine: 18.99840316
Total weight of Fluorine atoms in Actinium(III) fluoride: 18.99840316 x 3 = 56.99520949

Step 4: Calculate the molecular weight of Actinium(III) fluoride by adding up the total weight of all atoms.

Molecular weight of Actinium(III) fluoride: 227 (Actinium) + 56.99520949 (Fluorine) = 283.995209489

So the molecular weight of Actinium(III) fluoride is 283.995209489.
