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 Hydrogen chloride (HCl): 36.4607 (See Hydrogen Chloride (HCl) Molecular Weight Calculation)

Step 3: Calculate the total weight of each atom in a Y-27632 dihydrochloride molecule by multiplying its atomic weight by its number.

Number of Carbon atoms in Y-27632 dihydrochloride: 14
Atomic weight of Carbon (C): 12.0107
Total weight of Carbon atoms in Y-27632 dihydrochloride: 12.0107 x 14 = 168.1498

Number of Hydrogen atoms in Y-27632 dihydrochloride: 21
Atomic weight of Hydrogen (H): 1.008
Total weight of Hydrogen atoms in Y-27632 dihydrochloride: 1.008 x 21 = 21.168

Number of Nitrogen atoms in Y-27632 dihydrochloride: 3
Atomic weight of Nitrogen (N): 14.00674
Total weight of Nitrogen atoms in Y-27632 dihydrochloride: 14.00674 x 3 = 42.02022

Number of Oxygen atoms in Y-27632 dihydrochloride: 1
Atomic weight of Oxygen (O): 15.9994
Total weight of Oxygen atoms in Y-27632 dihydrochloride: 15.9994 x 1 = 15.9994

Number of Hydrogen chloride molecules in Y-27632 dihydrochloride: 2
Molecular weight of Hydrogen chloride (HCl): 36.4607
Total weight of Hydrogen chloride in Y-27632 dihydrochloride: 36.4607 x 2 = 72.9214

Step 4: Calculate the molecular weight of Y-27632 dihydrochloride by adding up the total weight of all atoms.

Molecular weight of Y-27632 dihydrochloride: 168.1498 (Carbon) + 21.168 (Hydrogen) + 42.02022 (Nitrogen) + 15.9994 (Oxygen) + 72.9214 (Hydrogen chloride) = 320.25882

So the molecular weight of Y-27632 dihydrochloride is 320.25882.
