# Americium Dioxide [AmO2] Molecular Weight Calculation

The molecular weight of Americium dioxide [AmO2] is 274.9988.

Americium dioxide [AmO2] is an inorganic compound of two elements: Americium (Am) and Oxygen (O). The molecular weight of Americium dioxide is 274.9988 which can be calculated by adding up the total weight (atomic weight multiplied by their number) of all its elements.

# CALCULATION PROCEDURE: Americium dioxide [AmO2] Molecular Weight Calculation

Step 1: Find out the chemical formula and determine constituent atoms and their number in an Americium dioxide molecule.
From the chemical formula, you will know different atoms and their number in an Americium dioxide molecule. The chemical formula of Americium dioxide is AmO2. From the chemical formula, you can find that one molecule of Americium dioxide consists of one Americium (Am) atom and two Oxygen (O) atoms.

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

Atomic weight of Americium (Am): 243 (Ref: Jlab-ele095, Lanl-95)
Atomic weight of Oxygen (O): 15.9994 (Ref: Jlab-ele008)

Step 3: Calculate the molecular weight of Americium dioxide by adding the total weight of all atoms.

Number of Americium atoms in Americium dioxide: 1
Atomic weight of Americium: 243
Total weight of Americium atoms in Americium dioxide: 243 x 1 = 243

Number of Oxygen (O) atoms in Americium dioxide: 2
Atomic weight of Oxygen: 15.9994
Total weight of Oxygen atoms in Americium dioxide: 15.9994 x 2 = 31.9988

Step 4: Calculate the molecular weight of Americium dioxide by adding up the total weight of all atoms.

Molecular weight of Americium dioxide: 243 (Americium) + 31.9988 (Oxygen) = 274.9988

So the molecular weight of Americium dioxide is 274.9988.
