# Ammonium Carbonate [(NH4)2CO3] Molecular Weight Calculation

The molecular weight of Ammonium carbonate [(NH4)2CO3] is 96.08638.

Ammonium carbonate [(NH4)2CO3] is an inorganic compound of four elements: Carbon, Hydrogen, Nitrogen, and Oxygen. The molecular weight of Ammonium carbonate is 96.08638 which can be calculated by adding up the total weight (atomic weight multiplied by their number) of Carbon, Hydrogen, Nitrogen, and Oxygen.

# CALCULATION PROCEDURE: Ammonium carbonate [(NH4)2CO3] Molecular Weight Calculation

Step 1: Find the chemical formula and determine constituent atoms and their number in an Ammonium carbonate molecule.
You will know different atoms and their number in an Ammonium carbonate molecule from the chemical formula. The chemical formula of Ammonium carbonate is C1H8O3N2. From the chemical formula of Ammonium carbonate, you can find that one molecule of Ammonium carbonate has one Carbon (C) atom, eight Hydrogen (H) atoms, three Oxygen (O) atoms, and two Nitrogen (N) atoms.

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

Atomic weight of Carbon (C): 12.0107 (Ref: Jlab-ele006)
Atomic weight of
Hydrogen (H): 1.008 (Ref: Lanl-1)
Atomic weight of Oxygen (O): 15.9994 (Ref: Jlab-ele008)
Atomic weight of Nitrogen (N): 14.00674 (Ref: Jlab-ele007)

Step 3: Calculate the total weight of each atom in an Ammonium carbonate molecule by multiplying its atomic weight by its number.

Number of Carbon atoms in Ammonium carbonate: 1
Atomic weight of
Carbon (C): 12.0107
Total weight of Carbon atoms in Ammonium carbonate: 12.0107 x 1 = 12.0107

Number of Hydrogen atoms in Ammonium carbonate: 8
Atomic weight of Hydrogen (H): 1.008
Total weight of Hydrogen atoms in Ammonium carbonate: 1.008 x 8 = 8.064

Number of Oxygen atoms in Ammonium carbonate: 3
Atomic weight of Oxygen (O): 15.9994
Total weight of Oxygen atoms in Ammonium carbonate: 15.9994 x 3 = 47.9982

Number of Nitrogen atoms in Ammonium carbonate: 2
Atomic weight of Nitrogen (N): 14.00674
Total weight of Nitrogen atoms in Ammonium carbonate: 14.00674 x 2 = 28.01348

Step 4: Calculate the molecular weight of Ammonium carbonate by adding up the total weight of all atoms.

Molecular weight of Ammonium carbonate: 12.0107 (Carbon) + 8.064 (Hydrogen) + 47.9982 (Oxygen) + 14.00674 (Nitrogen) = 96.08638

So the molecular weight of Ammonium carbonate is 96.08638.
