The molecular weight of Arsenic trifluoride [AsF₃] is 131.916804489.

Arsenic trifluoride [AsF₃] is an inorganic compound of two elements: Arsenic and Fluorine. The molecular weight of Arsenic trifluoride is 131.916804489 which can be calculated by adding up the total weight (atomic weight multiplied by their number) of all its elements.

CALCULATION PROCEDURE: Arsenic Trifluoride [AsF₃] Molecular Weight Calculation

Step 1: Find out the chemical formula and determine constituent atoms and their number in an Arsenic trifluoride molecule.
From the chemical formula, you will know different atoms and their number in an Arsenic trifluoride molecule. The chemical formula of Arsenic trifluoride is AsF₃. From the chemical formula, you can find that one molecule of Arsenic trifluoride consists of one Arsenic (As) atom and three Fluorine (F) atoms.

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

Atomic weight of Arsenic (As): 74.921595 (Ref: Jlab-ele033, ciaaw-arsenic)
Atomic weight of Fluorine (F): 18.998403163 (Ref: Pubchem-9, Ciaaw-fluorine)

Step 3: Calculate the molecular weight of Arsenic trifluoride by adding the total weight of all atoms.

Number of Arsenic atoms in Arsenic trifluoride: 1
Atomic weight of Arsenic: 74.921595
Total weight of Arsenic atoms in Arsenic trifluoride: 74.921595 x 1 = 74.921595

Number of Fluorine (F) atoms in Arsenic trifluoride: 3
Atomic weight of Fluorine: 18.998403163
Total weight of Fluorine atoms in Arsenic trifluoride: 18.998403163 x 3 = 56.995209489

Step 4: Calculate the molecular weight of Arsenic trifluoride by adding up the total weight of all atoms.

Molecular weight of Arsenic trifluoride: 74.921595 (Arsenic) + 56.995209489 (Fluorine) = 131.916804489

So the molecular weight of Arsenic trifluoride is 131.916804489.
