Molar and molecular weight of AsCl3O

• Relative molecular weight of AsCl3O: 197.28
• Molar mass of AsCl3O: 197.28 g/mol (0.19728 kg/mol)

Calculation of the relative molecular and molar mass of AsCl3O

• Mr[AsCl3O] = Ar[As] + Ar[Cl] * 3 + Ar[O] = 74.9216 + 35.453 * 3 + 15.9994 = 197.28
• Molar mass (kg/mol) = Mr[AsCl3O] : 1000 = 197.28 : 1000 = 0.19728 kg/mol

AsCl3O: percent composition by element

• Arsenic (As) = 74.9216 : 197.28 * 100 = 37.977 %
• Chlorine (Cl) = 106.359 : 197.28 * 100 = 53.913 %
• Oxygen (O) = 15.9994 : 197.28 * 100 = 8.11 %
