Molar and molecular weight of POCl3

• Molecular formula: POCl3 or Cl3OP
• Relative molecular weight of POCl3: 153.332162
• Molar mass of POCl3: 153.332162 g/mol (0.15333 kg/mol)

Calculation of the relative molecular and molar mass of POCl3

• Mr[POCl3] = Ar[Cl] * 3 + Ar[O] + Ar[P] = 35.453 * 3 + 15.9994 + 30.973762 = 153.332162
• Molar mass (kg/mol) = Mr[POCl3] : 1000 = 153.332162 : 1000 = 0.15333 kg/mol

POCl3: percent composition by element

• Chlorine (Cl) = 106.359 : 153.332162 * 100 = 69.365 %
• Oxygen (O) = 15.9994 : 153.332162 * 100 = 10.434 %
• Phosphorus (P) = 30.973762 : 153.332162 * 100 = 20.2 %
