The molecular weight of Ammonium acetate [CH3COONH4] is 77.08294.

Ammonium acetate (CH3COONH4) is an organic compound of four elements: Carbon, Hydrogen, Nitrogen, and Oxygen. The molecular weight of Ammonium acetate is 77.08294 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 acetate [CH3COONH4] Molecular Weight Calculation

Step 1: Find the chemical formula and determine constituent atoms and their number in an Ammonium acetate molecule.
You will know different atoms and their number in an Ammonium acetate molecule from the chemical formula. The chemical formula of Ammonium acetate is C2H7O2N. From the chemical formula of Ammonium acetate, you can find that one molecule of Ammonium acetate has two Carbon (C) atoms, seven Hydrogen (H) atoms, two 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 acetate molecule by multiplying its atomic weight by its number.

Number of Carbon atoms in Ammonium acetate: 2
Atomic weight of
Carbon (C): 12.0107
Total weight of Carbon atoms in Ammonium acetate: 12.0107 x 2 = 24.0214

Number of Hydrogen atoms in Ammonium acetate: 7
Atomic weight of Hydrogen (H): 1.008
Total weight of Hydrogen atoms in Ammonium acetate: 1.008 x 7 = 7.056

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

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

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

Molecular weight of Ammonium acetate: 24.0214 (Carbon) + 7.056 (Hydrogen) + 31.9988 (Oxygen) + 14.00674 (Nitrogen) = 77.08294

So the molecular weight of Ammonium acetate is 77.08294.
