# Ammonium Bicarbonate [NH4HCO3] Molecular Weight Calculation

The molecular weight of Ammonium bicarbonate [NH4HCO3] is 79.05564.

Ammonium bicarbonate [NH4HCO3] is an inorganic compound of four elements: Carbon, Hydrogen, Nitrogen, and Oxygen. The molecular weight of Ammonium bicarbonate is 79.05564 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 bicarbonate [NH4HCO3] Molecular Weight Calculation

Step 1: Find the chemical formula and determine constituent atoms and their number in an Ammonium bicarbonate molecule.
You will know different atoms and their number in an Ammonium bicarbonate molecule from the chemical formula. The chemical formula of Ammonium bicarbonate is C1H5O3N1. From the chemical formula of Ammonium bicarbonate, you can find that one molecule of Ammonium bicarbonate has one Carbon (C) atom, five Hydrogen (H) atoms, three Oxygen (O) atoms, and one Nitrogen (N) atom.

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 bicarbonate molecule by multiplying its atomic weight by its number.

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

Number of Hydrogen atoms in Ammonium bicarbonate: 5
Atomic weight of Hydrogen (H): 1.008
Total weight of Hydrogen atoms in Ammonium bicarbonate: 1.008 x 5 = 5.04

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

Number of Nitrogen atoms in Ammonium bicarbonate: 1
Atomic weight of Nitrogen (N): 14.00674
Total weight of Nitrogen atoms in Ammonium bicarbonate: 14.00674 x 1 = 14.00674

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

Molecular weight of Ammonium bicarbonate: 12.0107 (Carbon) + 5.04 (Hydrogen) + 47.9982 (Oxygen) + 14.00674 (Nitrogen) = 79.05564

So the molecular weight of Ammonium bicarbonate is 79.05564.
