The molecular weight of Serine [C3H7NO3] is 105.09304.
Serine (C3H7NO3) is an organic compound of five elements: Carbon, Hydrogen, Nitrogen, and Oxygen. The molecular weight of Serine is 105.09304 which can be calculated by adding up the total weight (atomic weight multiplied by their number) of all its elements.
CALCULATION PROCEDURE: Serine [C3H7NO3] Molecular Weight Calculation
Step 1: Find out the chemical formula and determine constituent atoms and their number in a Serine molecule.
From the chemical formula, you will know different atoms and their number in a Serine molecule. The chemical formula of Serine is C3H7NO3. From the chemical formula of Serine, you can find that one molecule of Serine consists of three Carbon (C) atoms, seven Hydrogen (H) atoms, one Nitrogen (N) atom, and three Oxygen 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)
Step 3: Calculate the total weight of each atom in an Alanine molecule by multiplying its atomic weight by its number.
Number of Carbon atoms in Serine: 3
Atomic weight of Carbon (C): 12.0107
Total weight of Carbon atoms in Serine: 12.0107 x 3 = 36.0321
Number of Hydrogen atoms in Serine: 7
Atomic weight of Hydrogen (H): 1.008
Total weight of Hydrogen atoms in Serine: 1.008 x 7 = 7.056
Number of Nitrogen atoms in Serine: 1
Atomic weight of Nitrogen (N): 14.00674
Total weight of Nitrogen atoms in Serine: 14.00674 x 1 = 14.00674
Number of Oxygen atoms in Serine: 3
Atomic weight of Oxygen (O): 15.9994
Total weight of Oxygen atoms in Serine: 15.9994 x 3 = 47.9982
Step 4: Calculate the molecular weight of Serine by adding up the total weight of all atoms.
Molecular weight of Serine: 36.0321 (Carbon) + 7.056 (Hydrogen) + 14.00674 (Nitrogen) + 47.9982 (Oxygen) = 105.09304
So the molecular weight of Serine is 105.09304.
