CALCULATION PROCEDURE: G-418 disulfate salt  [C20H40N4O10.2H2SO4] Molecular Weight Calculation

Step 1: Find out the chemical formula and determine constituent atoms and their number in a G-418 disulfate salt molecule.
You will know different atoms and their number in a G-418 disulfate salt molecule from the chemical formula. The chemical formula of G-418 disulfate salt is C20H40N4O10.2H2SO4. From the chemical formula, you can find that one molecule of G-418 disulfate salt consists of twenty Carbon (C) atoms, forty Hydrogen (H) atoms, four Nitrogen (N) atoms, ten Oxygen atoms, and two sulfuric acid molecules.

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)
Molecular weight of
Sulfuric acid [H2SO4]: 98.0796 (see molecular weight calculation of Sulfuric acid [H2SO4])

Step 3: Calculate the total weight of each atom in a G-418 disulfate salt molecule by multiplying its atomic weight by its number.

Number of Carbon atoms in G-418 disulfate salt: 20
Atomic weight of Carbon (C): 12.0107
Total weight of Carbon atoms in G-418 disulfate salt: 12.0107 x 14 = 240.214

Number of Hydrogen atoms in G-418 disulfate salt: 40
Atomic weight of Hydrogen (H): 1.008
Total weight of Hydrogen atoms in G-418 disulfate salt: 1.008 x 40 = 40.32

Number of Nitrogen atoms in G-418 disulfate salt: 4
Atomic weight of Nitrogen (N): 14.00674
Total weight of Nitrogen atoms in G-418 disulfate salt: 14.00674 x 4 = 56.02696

Number of Oxygen atoms in G-418 disulfate salt: 10
Atomic weight of Oxygen (O): 15.9994
Total weight of Oxygen atoms in G-418 disulfate salt: 15.9994 x 10 = 159.994

Number of sulfuric acid molecules in G-418 disulfate salt: 2
Molecular weight of Sulfuric acid (H2SO4): 98.0796
Total weight of Sulfuric acid in G-418 disulfate salt: 36.4607 x 2 = 196.1592

Step 4: Calculate the molecular weight of G-418 disulfate salt by adding up the total weight of all atoms.

Molecular weight of G-418 disulfate salt: 240.214 (Carbon) + 40.32 (Hydrogen) + 56.02696 (Nitrogen) + 159.994 (Oxygen) + 196.1592 (Sulfuric acid) = 692.71416

So the molecular weight of G-418 disulfate salt is 692.71416.
