Molar and molecular weight of C3O2

• Relative molecular weight of C3O2: 68.0309
• Molar mass of C3O2: 68.0309 g/mol (0.06803 kg/mol)

Calculation of the relative molecular and molar mass of C3O2

• Mr[C3O2] = Ar[C] * 3 + Ar[O] * 2 = 12.0107 * 3 + 15.9994 * 2 = 68.0309
• Molar mass (kg/mol) = Mr[C3O2] : 1000 = 68.0309 : 1000 = 0.06803 kg/mol

C3O2: percent composition by element

• Carbon (C) = 36.0321 : 68.0309 * 100 = 52.964 %
• Oxygen (O) = 31.9988 : 68.0309 * 100 = 47.036 %
