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 Sodium (Na): 22.98976928 (Ref: Ciaaw-sodium)
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 Ponceau S (tetrasodium salt) molecule by multiplying its atomic weight by its number.

Number of Carbon atoms in Ponceau S (tetrasodium salt): 22
Atomic weight of Carbon (C): 12.0107

Number of Hydrogen atoms in Ponceau S (tetrasodium salt): 12
Atomic weight of Hydrogen (H): 1.008
Total weight of Hydrogen atoms in Ponceau S (tetrasodium salt): 1.008 x 12 = 12.096

Number of Nitrogen atoms in Ponceau S (tetrasodium salt): 4
Atomic weight of Nitrogen (N): 14.00674
Total weight of Nitrogen atoms in Ponceau S (tetrasodium salt): 14.00674 x 4 = 56.02696

Number of Sodium atoms in Ponceau S (tetrasodium salt): 4
Atomic weight of Sodium (Na): 22.98976928
Total weight of Sodium atoms in Ponceau S (tetrasodium salt): 22.98976928 x 4 = 91.95907712

Number of Oxygen atoms in Ponceau S (tetrasodium salt): 13
Atomic weight of Oxygen (O): 15.9994
Total weight of Oxygen atoms in Ponceau S (tetrasodium salt): 15.9994 x 13 = 207.9922

Number of Sulfur atoms in Ponceau S (tetrasodium salt): 4
Atomic weight of Sulfur (S): 32.066
Total weight of Sulfur atoms in Ponceau S (tetrasodium salt): 32.066 x 4 = 128.264

Step 4: Calculate the molecular weight of Ponceau S (tetrasodium salt) by adding up the total weight of all atoms.

Molecular weight of Ponceau S (tetrasodium salt): 264.2354 (Carbon) + 12.096 (Hydrogen) + 56.02696 (Nitrogen) + 91.95907712 (Sodium) + 207.9922 (Oxygen) + 128.264 (Sulfur) = 760.5736371

So the molecular weight of Ponceau S (tetrasodium salt) is 760.5736371.
