The molecular weight of Calcium acetate [(CH₃COO)₂Ca] is 158.1664.

Calcium acetate [(CH₃COO)₂Ca] is an organic compound of four elements: Carbon, Hydrogen, Calcium, and Oxygen. The molecular weight of Calcium acetate is 158.1664 which can be calculated by adding up the total weight (atomic weight multiplied by their number) of Carbon, Hydrogen, Calcium, and Oxygen.

CALCULATION PROCEDURE: Calcium acetate [(CH₃COO)₂Ca] Molecular Weight Calculation

Step 1: Find out the chemical formula and determine constituent atoms and their number in a Calcium acetate molecule.
You will know different atoms and their number in a Calcium acetate molecule from the chemical formula. The chemical formula of Calcium acetate is [(CH₃COO)₂Ca]. From the chemical formula, you can find that one molecule of Calcium acetate has four Carbon (C) atoms, six Hydrogen (H) atoms, four Oxygen (O) atoms, and one Calcium (Ca) 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 Calcium (Ca): 40.078 (Ref: Pubchem-20, Ciaaw-calcium)

Step 3: Calculate the total weight of each atom in a Calcium acetate molecule by multiplying its atomic weight by its number.

Number of Carbon atoms in Calcium acetate: 4
Atomic weight of Carbon (C): 12.0107
Total weight of Carbon atoms in Calcium acetate: 12.0107 x 4 = 48.0428

Number of Hydrogen atoms in Calcium acetate: 6
Atomic weight of Hydrogen (H): 1.008
Total weight of Hydrogen atoms in Calcium acetate: 1.008 x 6 = 6.048

Number of Oxygen atoms in Calcium acetate: 4
Atomic weight of Oxygen (O): 15.9994
Total weight of Oxygen atoms in Calcium acetate: 15.9994 x 4 = 63.9976

Number of Calcium atoms in Calcium acetate: 1
Atomic weight of Calcium (Ca): 40.078
Total weight of Calcium atoms in Calcium acetate: 40.078 x 1 = 40.078

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

Molecular weight of Calcium acetate: 48.0428 (Carbon) + 6.048 (Hydrogen) + 63.9976 (Oxygen) + 40.078 (Calcium) = 158.1664

So the molecular weight of Calcium acetate is 158.1664.
