From the chemical formula, you can find that one molecule of 2,6-Dichloropyridine-3-carboxaldehyde consists of six Carbon (C) atoms, three Hydrogen (H) atoms, two Chlorine atoms, one Nitrogen (N) atom, and one Oxygen 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
Chlorine (Cl): 35.4527 (Ref: jlab-ele017)
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 2,6-Dichloropyridine-3-carboxaldehyde molecule by multiplying its atomic weight by its number.

Number of Carbon atoms in 2,6-Dichloropyridine-3-carboxaldehyde: 6
Atomic weight of Carbon (C): 12.0107
Total weight of Carbon atoms in 2,6-Dichloropyridine-3-carboxaldehyde: 12.0107 x 6 = 72.0642

Number of Hydrogen atoms in 2,6-Dichloropyridine-3-carboxaldehyde: 3
Atomic weight of Hydrogen (H): 1.008
Total weight of Hydrogen atoms in 2,6-Dichloropyridine-3-carboxaldehyde: 1.008 x 3 = 3.024

Number of Chlorine atoms in 2,6-Dichloropyridine-3-carboxaldehyde: 2
Atomic weight of Chlorine (Cl): 35.4527
Total weight of Chlorine atoms in 2,6-Dichloropyridine-3-carboxaldehyde: 35.4527 x 2 = 70.9054

Number of Nitrogen atoms in 2,6-Dichloropyridine-3-carboxaldehyde: 1
Atomic weight of Nitrogen (N): 14.00674
Total weight of Nitrogen atoms in 2,6-Dichloropyridine-3-carboxaldehyde: 14.00674 x 1 = 14.00674

Number of Oxygen atoms in 2,6-Dichloropyridine-3-carboxaldehyde: 1
Atomic weight of Oxygen (O): 15.9994
Total weight of Oxygen atoms in 2,6-Dichloropyridine-3-carboxaldehyde: 15.9994 x 1 = 15,9994

Step 4: Calculate the molecular weight of 2,6-Dichloropyridine-3-carboxaldehyde by adding up the total weight of all atoms.

Molecular weight of 2,6-Dichloropyridine-3-carboxaldehyde: 72.0642 (Carbon) + 3.024 (Hydrogen) + 70.9054 (Chlorine) + 14.00674 (Nitrogen) + 15,9994 (Oxygen) = 175.99974

So the molecular weight of 2,6-Dichloropyridine-3-carboxaldehyde is 175.99974.
