CALCULATION PROCEDURE: Adenosine triphosphate  [C10H15N5O10P2] Molecular Weight Calculation

Step 1: Find out the chemical formula and determine constituent atoms and their number in an Adenosine triphosphate molecule.
From the chemical formula, you will know different atoms and their number in an Adenosine triphosphate molecule. Chemical formula of Adenosine triphosphate is C10H15N5O10P2. From the chemical formula of Adenosine triphosphate, you can find that one molecule of Adenosine triphosphate consists of ten Carbon (C) atoms, fifteen Hydrogen (H) atoms, five Nitrogen (N) atoms, ten Oxygen atoms, and two Phosphorus (P) 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 Nitrogen (N): 14.00674 (Ref: Jlab-ele007)
Atomic weight of Oxygen (O): 15.9994 (Ref: Jlab-ele008)
Atomic weight of
Phosphorus (P): 30.973761998 (Ref: Jlab-ele015)

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

Number of Carbon atoms in Adenosine triphosphate: 10
Atomic weight of Carbon (C): 12.0107
Total weight of Carbon atoms in Adenosine triphosphate: 12.0107 x 10 = 120.107

Number of Hydrogen atoms in Adenosine triphosphate: 15
Atomic weight of Hydrogen (H): 1.008
Total weight of Hydrogen atoms in Adenosine triphosphate: 1.008 x 15 = 16.128

Number of Nitrogen atoms in Adenosine triphosphate: 5
Atomic weight of Nitrogen (N): 14.00674
Total weight of Nitrogen atoms in Adenosine triphosphate: 14.00674 x 5 = 70.0337

Number of Oxygen atoms in Adenosine triphosphate: 10
Atomic weight of Oxygen (O): 15.9994
Total weight of Oxygen atoms in Adenosine triphosphate: 15.9994 x 10 = 207.9922

Number of Phosphorus atoms in Adenosine triphosphate: 2
Atomic weight of Phosphorus (P): 30.973761998
Total weight of Phosphorus atoms in Adenosine triphosphate: 30.973761998 x 2 = 92.921285994

Step 4: Calculate the molecular weight of Adenosine triphosphate by adding up the total weight of all atoms.

Molecular weight of Adenosine triphosphate: 120.107 (Carbon) + 16.128 (Hydrogen) + 70.0337 (Nitrogen) + 207.9922 (Oxygen) + 92.921285994 (Phosphorus) = 507.182185994

So the molecular weight of Adenosine triphosphate is 507.182185994.
