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.
