Molar and molecular weight of CCl2

• Relative molecular weight of CCl2: 82.9167
• Molar mass of CCl2: 82.9167 g/mol (0.08292 kg/mol)

Calculation of the relative molecular and molar mass of CCl2

• Mr[CCl2] = Ar[C] + Ar[Cl] * 2 = 12.0107 + 35.453 * 2 = 82.9167
• Molar mass (kg/mol) = Mr[CCl2] : 1000 = 82.9167 : 1000 = 0.08292 kg/mol

CCl2: percent composition by element

• Carbon (C) = 12.0107 : 82.9167 * 100 = 14.485 %
• Chlorine (Cl) = 70.906 : 82.9167 * 100 = 85.515 %
