Adenosine monophosphate (C10H14N5O7P) Molecular Weight CalculationAdenosine monophosphate (C10H14N5O7P) is an organic compound of five elements: Carbon, Hydrogen, Nitrogen, Oxygen and Phosphorus. The molecular weight of Adenosine monophosphate is 347.222261998 which can be calculated by adding up the total weight (atomic weight multiplied by their number) of all its elements.

CALCULATION PROCEDURE: Adenosine monophosphate  [C10H14N5O7P] Molecular Weight Calculation

Step 1: Find out the chemical formula and determine constituent atoms and their number in an Adenosine monophosphate molecule.
From the chemical formula, you will know different atoms and their number in an Adenosine monophosphate molecule. Chemical formula of Adenosine monophosphate is C10H14N5O7P. From the chemical formula of Adenosine monophosphate, you can find that one molecule of Adenosine monophosphate consists of ten Carbon (C) atoms, fourteen Hydrogen (H) atoms five Nitrogen (N) atoms, seven Oxygen atoms and one Phosphorus (P) 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 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 monophosphate molecule by multiplying its atomic weight by its number.

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

Number of Hydrogen atoms in Adenosine monophosphate: 14
Atomic weight of Hydrogen (H): 1.008
Total weight of Hydrogen atoms in Adenosine monophosphate: 1.008 x 14 = 14.112

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

Number of Oxygen atoms in Adenosine monophosphate: 7
Atomic weight of Oxygen (O): 15.9994
Total weight of Oxygen atoms in Adenosine monophosphate: 15.9994 x 7 = 111.9958

Number of Phosphorus atoms in Adenosine monophosphate: 1
Atomic weight of Phosphorus (P): 30.973761998
Total weight of Phosphorus atoms in Adenosine monophosphate: 30.973761998 x 1 = 30.973761998

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

Molecular weight of Adenosine monophosphate: 120.107 (Carbon) + 14.112 (Hydrogen) + 70.0337 (Nitrogen) + 111.9958 (Oxygen) + 30.973761998 (Phosphorus) = 347.222261998

So the molecular weight of Adenosine monophosphate is 347.222261998.
