CALCULATION PROCEDURE: MOPS (4-Morpholinepropanesulfonic acid)  [C₇H₁₅NO₄S] Molecular Weight Calculation

Step 1: Find the chemical formula and determine constituent atoms and their number in a MOPS (4-Morpholinepropanesulfonic acid) molecule.
You will know different atoms and their number in a MOPS (4-Morpholinepropanesulfonic acid) molecule from the chemical formula. The chemical formula of MOPS (4-Morpholinepropanesulfonic acid) is C₇H₁₅NO₄S. From the chemical formula, you can find that one molecule of MOPS (4-Morpholinepropanesulfonic acid) consists of seven Carbon (C) atoms, fifteen Hydrogen (H) atoms, one Nitrogen (N) atom, four Oxygen atoms, and one Sulfur (S) 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 Sulfur (S): 32.066 (Ref: Jlab-ele016)

Step 3: Calculate the total weight of each atom in a MOPS (4-Morpholinepropanesulfonic acid) molecule by multiplying its atomic weight by its number.

Number of Carbon atoms in MOPS (4-Morpholinepropanesulfonic acid): 7
Atomic weight of Carbon (C): 12.0107
Total weight of Carbon atoms in MOPS (4-Morpholinepropanesulfonic acid): 12.0107 x 7 = 84.0749

Number of Hydrogen atoms in MOPS (4-Morpholinepropanesulfonic acid): 15
Atomic weight of Hydrogen (H): 1.008
Total weight of Hydrogen atoms in MOPS (4-Morpholinepropanesulfonic acid): 1.008 x 15 = 15.12

Number of Nitrogen atoms in MOPS (4-Morpholinepropanesulfonic acid): 1
Atomic weight of Nitrogen (N): 14.00674
Total weight of Nitrogen atoms in MOPS (4-Morpholinepropanesulfonic acid): 14.00674 x 1 = 14.00674

Number of Oxygen atoms in MOPS (4-Morpholinepropanesulfonic acid): 4
Atomic weight of Oxygen (O): 15.9994
Total weight of Oxygen atoms in MOPS (4-Morpholinepropanesulfonic acid): 15.9994 x 4 = 63.9976

Number of Sulfur atoms in MOPS (4-Morpholinepropanesulfonic acid): 1
Atomic weight of Sulfur (S): 32.066
Total weight of Sulfur atoms in MOPS (4-Morpholinepropanesulfonic acid): 32.066 x 1 = 32.066

Step 4: Calculate the molecular weight of MOPS (4-Morpholinepropanesulfonic acid) by adding up the total weight of all atoms.

Molecular weight of MOPS (4-Morpholinepropanesulfonic acid): 84.0749 (Carbon) + 15.12 (Hydrogen) + 14.00674 (Nitrogen) + 63.9976 (Oxygen) + 32.066 (Sulfur) = 209.26524

So the molecular weight of MOPS (4-Morpholinepropanesulfonic acid) is 209.26524.
