# Arsenic(III) Telluride [As2Te3] Molecular Weight Calculation

The molecular weight of Arsenic(III) telluride [As2Te3] is 532.64319. Arsenic(III) telluride [As2Te3] is an inorganic compound of two elements: Arsenic (As) and Tellurium (Te). The molecular weight of Arsenic(III) telluride is 532.64319 which can be calculated by adding up the total weight (atomic weight multiplied by their number) of all its elements.

# CALCULATION PROCEDURE: Arsenic(III) telluride [As2Te3] Molecular Weight Calculation

Step 1: Find out the chemical formula and determine constituent atoms and their number in an Arsenic(III) telluride molecule.
From the chemical formula, you will know different atoms and their number in an Arsenic(III) telluride molecule. The chemical formula of Arsenic(III) telluride is As2Te3. From the chemical formula, you can find that one molecule of Arsenic(III) telluride consists of two Arsenic (As) atoms and three Tellurium (Te) 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 Tellurium (Te): 127.6 (Ref: Jlab-ele052, ciaaw-tellurium)

Step 3: Calculate the molecular weight of Arsenic(III) telluride by adding the total weight of all atoms.

Number of Arsenic atoms in Arsenic(III) telluride: 2
Atomic weight of Arsenic: 74.921595
Total weight of Arsenic atoms in Arsenic(III) telluride: 74.921595 x 2 = 149.84319

Number of Tellurium (Te) atoms in Arsenic(III) telluride: 3
Atomic weight of Tellurium: 127.6
Total weight of Tellurium atoms in Arsenic(III) telluride: 127.6 x 3 = 382.8

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

Molecular weight of Arsenic(III) telluride: 149.84319 (Arsenic) + 382.8 (Tellurium) = 532.64319

So the molecular weight of Arsenic(III) telluride is 532.64319.
