Valine (C5H11NO2) is an organic compound of five elements: Carbon, Hydrogen, Nitrogen, and Oxygen. The molecular weight of Valine is 117.14704 which can be calculated by adding up the total weight (atomic weight multiplied by their number) of all its elements.
CALCULATION PROCEDURE: Valine [C5H11NO2] Molecular Weight Calculation
Step 1: Find out the chemical formula and determine constituent atoms and their number in a Valine molecule.
From the chemical formula, you will know different atoms and their number in a Valine molecule. The chemical formula of Valine is C5H11NO2. From the chemical formula of Valine, you can find that one molecule of Valine consists of five Carbon (C) atoms, eleven Hydrogen (H) atoms, one Nitrogen (N) atom, and two 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 a Valine molecule by multiplying its atomic weight by its number.
Number of Carbon atoms in Valine: 5
Atomic weight of Carbon (C): 12.0107
Total weight of Carbon atoms in Valine: 12.0107 x 5 = 60.0535
Number of Hydrogen atoms in Valine: 11
Atomic weight of Hydrogen (H): 1.008
Total weight of Hydrogen atoms in Valine: 1.008 x 11 = 11.088
Number of Nitrogen atoms in Valine: 1
Atomic weight of Nitrogen (N): 14.00674
Total weight of Nitrogen atoms in Valine: 14.00674 x 1 = 14.00674
Number of Oxygen atoms in Valine: 2
Atomic weight of Oxygen (O): 15.9994
Total weight of Oxygen atoms in Valine: 15.9994 x 2 = 31.9988
Step 4: Calculate the molecular weight of Valine by adding up the total weight of all atoms.
Molecular weight of Valine: 60.0535 (Carbon) + 11.088 (Hydrogen) + 14.00674 (Nitrogen) + 31.9988 (Oxygen) = 117.14704
So the molecular weight of Valine is 117.14704.
