Molar and molecular weight of CCl2O

• Molecular formula: CCl2O or COCl2
• Relative molecular weight of CCl2O: 98.9161
• Molar mass of CCl2O: 98.9161 g/mol (0.09892 kg/mol)

Calculation of the relative molecular and molar mass of CCl2O

• Mr[CCl2O] = Ar[C] + Ar[Cl] * 2 + Ar[O] = 12.0107 + 35.453 * 2 + 15.9994 = 98.9161
• Molar mass (kg/mol) = Mr[CCl2O] : 1000 = 98.9161 : 1000 = 0.09892 kg/mol

CCl2O: percent composition by element

• Carbon (C) = 12.0107 : 98.9161 * 100 = 12.142 %
• Chlorine (Cl) = 70.906 : 98.9161 * 100 = 71.683 %
• Oxygen (O) = 15.9994 : 98.9161 * 100 = 16.175 %
